| In searching for a new boat, I've come across a leftover new on the floor 2012 Alumacraft Navigator with a 90 Yamaha. I have to say I'm really impressed with the layout and fit/finish. I'd love to hear from some Navigator owners about this boat's strengths and drawbacks, and top speed 90 Yami owners are seeing with this rig! |

Location: Aurora IL | Ive got a 2008 nav with a 115 etec. Best boat Ive ever owned. Well built, stable, roomy, love that all platforms and side lockers are the same height, you can walk a fish all the way around the boat if needed. With the 115 2 stroke mine will go about 45 with gear and 2 guys. 90 may be a bit small if its a 17 footer but on the 16 that boat would move. On the 175 the right rod locker will take 8 footers. I think you would love the boat. Bill |

| Second year fishing out of a 165 CS with a 75 E-Tec and it is a pleasure every time I'm on the water. The layout is hard to beat in a 16' aluminum v-hull. As stated, rod lockers fit 8' rods on each side, though the starboard side can be modified to accomodate an 8'6". Plenty of storage and the decks are at a great height for figure-eights. |

| Thanks for the replies so far. It is the 175 with a 90. If anyone is running this set up, top speed? |

Location: WI | I have a 175 tourney pro with a 135 2 stroke. It does 52 with two guys and gear. See If you can get a 115 put on it. I wouldn't want smaller than that. The 175 hull is 17'10" and a 90 would struggle imo. I would guess that it would only do 32 or so with no holeshot. Absulutly love the alumacraft though.

Location: Elk River, Minnesota | Hiya,
Assuming this is a 90hp four stroke, you are better off than the two stroke. If it is the two stroke, you will be very disappointed. I have the first year model boat of the navigator 165 with the 90 inch beam (2005) and had a 90 yami two stroke on it. Needless to say, it was a bit sluggish out of the hole, and would top out at about 37. After a few testing mods like carbon fiber reeds, a shaved head, and exhaust tuner, and a 4" manual set back plate, I managed to get it to 40, but was still slow out of the hole.
I upgraded the motor to a Johnson 90hp 2 stroke and without any mods, I can hit 43 in the cooler months and water. Mid summer it is 42. Hole shot is much better as the increase in displacement made a huge difference.
On the 175 series of boats, I would say you will be right around 40 - 41mph if set up for efficient running. A steel prop will help a few things such as allowing you to move the motor up a couple of holes which will increase top end without sacrificing too much in handling.
No matter what, the layout of the navigator series is hard to beat. plenty of room up front, easy to rig to your liking, and manageable for smaller waters while still being able to tackle big stuff. Dry ride given you don't over-drive the conditions. Stable platform all around.

| I have a 175 cs with a 115 4 stroke. It will do 40 fully loaded. Great rig. I had to add a bigger rear casting deck, but the rest of the boat was great. |

Location: Mayville, WI | I'll echo the comments above about the great layout - hard to beat! I run a 165 tiller w/ 75 yamaha (same block as the 90) and expect the 90 won't be too bad on the 175. I get a great hole shot & top out just under 38 with stock prop. VMS is probably right on the money for how it will perform.
Like cbuf, I increased the back deck a bit (18"), but that's my only issue as I usually give up the front when fishing with others. |

| You want at least the 115 on it, they are rated for a 150. This boat is the bomb for slaying muskys. Bought mine in 2011 and it has the 115 yama on it, the place i bought it from told me that you dont want nothing less than a 115. Like cbuf said 40 fully loaded and 43 to 44 by myself. Great boat great lay-out. I think that the 90 would be working to hard and you will go through alot of gas. Good luck to ya. |

Location: Elk River, Minnesota | Hiya,
How hard the motor works can be dealt with through correct pitch and diameter of the prop. So...no worries on gas or lugging the motor if it is propped correctly. Heck...if the tiller models are set up for (I believe) 75 hp, a 90 will work just fine...it won't be a speed demon, but it will get the job done with the proper set-up.
Many of the 175's out there were set up with 115 hp as it keeps price down yet fast enough to work well with the boat for handling and all around use. The 90 won't be far behind that.
In the best-case scenario, maxing out the HP at 150 is the way to go as higher displacement means better low end performance...especially when you need it, and get you great top end as well....again, only if propped for efficient running.
If you do go with the rig you are looking at and find it is not getting you out of the hole or not performing quite like you expected, shoot me a message real quick..I'll help if I can.

Location: MN | So what else can you do besides run stainless and make sure your WOT is where it should be? I run a pro v tiller and use the largest diameter prop and pitch it where I'm near max WOT.
Thanks

Location: Wisconsin | I have a 2011 175CS. I spent quite a bit of time researching engines and went with a 130 Etec over a 150. With the Etecs, the 150 jumps up to a 6 cyl and weighs more than the 130 and burns more fuel. I get 40-45 on mine which I think was right in line with the 150. Plus, the 150 cost more. I went with Etec over Merc for a bunch of reasons, but to each is own.
I would agree with what is said here, the 90 will be WAY underpowered for that boat. It will work, but you will find out right away it will be a pain in the ass even if lightly loaded. I always suggest going max HP for a boat, but a 125 would work great as well. Good luck.

Location: Hayward, WI | The Navigator series are a great layout for musky fishing. I have the older one, before they increased the width and fancied them up a little. My Navigator is now called the "Classic." I've fished out of the new style 165 and it's very nice. Feels a little more solid in big waves than my older 165 does. I'd have to think the 175 is even better.
I'm a tiller guy, but if I was looking into a console I do think I'd want a 115+ on that boat. But, like VMS said if you prop it right it will work, it just won't be very fast. |

Location: Crystal Lake, IL | I just bought a 2012 Nav 175 CS a couple months ago. It has a 125 Merc on the back. I hit about 42 fully loaded with 2 people. The layout of this boat is incredible and I absolutely love fishing out of it. With the right people in the boat, you could easily musky fish 4 people out of it. Plenty of storage and the counsel side rod box will hold up to 8 footers. I can squeeze an 8'6 in there but you have to flex the rod a bit, so probably not a good idea. I don't know how much less power you'll get with the 90, but the boat won't be fast. To some people that doesn't really matter and it becomes a factor of what you can afford and/or are willing to spend on a new boat. Regardless of the motor, you won't be dissappointed fishing out of it! Send me a PM with their asking price, you should be able to get a realllllly good deal on it with a 90 on there. |

Location: Crystal Lake, IL | cbuf and scmuskies - do you guys have any pictures of the rear casting deck extension? I've already started thinking about that addition and curious how you guys went about it. Thanks! |

Location: Mayville, WI | Attached - used 3/4 marine ply, 2x1 stingers along the sides & one down the middle, poly resin over the whole thing, carpeted it, then bolted it right in. Made it so I can take off the seat & push the seat pole down flush w/ the floor. Plenty of space!

Hi Nick,
Max diameter is good for handling, but in order to run a big eared prop, the pitch must come down. In maximizing the efficiency of running any boat, a balance must be struck between diameter and pitch for what you are looking for out of the rig. If you want speed, going smaller diameter and higher pitch can get you there, but you sacrifice handling and hole-shot because you are reducing the amount of surface area on the prop for grabbing water. Some of that can be offset with vent holes in the prop hub to help hole shot, as the motor spins up to a higher rpm when the prop grabs. Adding cupping can add handling characteristics, bow lift, stern lift, etc depending on where the cupping of the fin is added, giving even more options for what you want your boat to do.
Lots more could be discussed as well, but there are lots of options available..
Steve

Location: Madison, WI | Friend has a navigator with a 90 and it really dogs. He isnt thrilled with it and kicks himself for not getting more motor. Says he is getting mid to low 30s tops and that WOT which isnt necessarily good for the motor. I wouldnt go with anything under 115 for power.
I have a 2009 with a 150 opti. Love the boat. I get 46-47 WOT with two dudes and gear. Most times im running at 3000 RPMs nice and easy and crusing along at 25-35 mph. My WOT throttle only reads about 5100-5200 RPM. I may need to start playing the prop game if guys are getting 50+. I am running a 19" SS.

| I went 18" so I can fit like 20 plano boxes standing up underneath the deck, across back. I also left a cutout of 2 inch on the drivers side,so I can store my net, with the handle hanging off the back of the deck. This way the net stands up behind the drive out of the way and is always ready to go. I'll see if I can dig up pictures. For the motor I would say 90 is to small.

I assume you are talking Competitor Series and Classic Series when you say CS? |

CS is single console, basically trim level of your chosen model - Tiller, CS, & Sport (full windshield). Competitor & Classic are different models (so is the navigator). |
