| Hi all, just looking at a used boat, and i believe it has a 140 h.p. on it, but its
only rated for a 130 or 135..
would this be an issue?
its a 4 stroke, so probably lighter than the original optimax it came with..
Thanks |

| Talk to your insurance company for possible implications. If common sense was a factor at all for this I would say there is zero issue. If the 140 is a Johnsuzki it is probably heavier than a 135 opti, but we aren't talking 100s of pounds or anything.
From everything I have read you won't like what your insurance company tells you. HP ratings are a strange thing. The boat will be slower with a 140 4 stroke compared to a 135 opti but not acceptable to your insurance company.
Just be glad you aren't looking at tiller boats. HP ratings are an even bigger debacle. |

| A four stroke weights more than a two stroke of the same horsepower that Ive seen, I would be worried about the boats transom if you were to put a more horsepower outboard on it than what on the coastguard plate says what that paticuler boat is rated for. |

Location: Elk River, MN | 5-10hp isn't much of a difference but its still above the max, just like speeding they can get you going 5 over. Sometimes you can get a boat re-certified for a little more power if you try and work with the coast guard. I doubt you would ever have a problem with the law out on the water, but if it ever came down to an insurance claim you could get stiffed. |

It's 2015...anything goes, no one will care. Run it. |

Location: Contrarian Island | I would agree, if you can get insurance just fine, and someone else put it on the boat, buy it if you like it... a friend has a Ranger 690 tiller rated for 90 and he bought it with a 100 hp Yammy 4 stroke...no issues... good rig. buy it and run it! |

Location: Hayward, WI | Per WI regulations: "Overpowering is providing more power than is needed. It is illegal to sell, equip, operate, or allow others to operate a boat with any motor or other propulsion machinery beyond its safe power capacity."
Doesn't say how safe power capacity is determined. Not sure if they use the CG plate?

This is what I was thinking.
Or if you should ever get into some kind of accident with the boat, it could come back up. |

Location: Contrarian Island | and the last time a boat was actually checked for it's HP rating.....ummmmm how about never! 
it's illegal to speed too....

Location: Elk River, MN | I agree 100% that the likelihood of being checked is slim, but it only takes one crabby CO to ruin your day. The bigger issue I see with an overpowered motor is the insurance side of it, you have an accident or any type of issue, your claim could get denied, the insurance company will look for anything to not have to pay a claim. |

| I wouldn't highly recommend it but I usually side on the cautious side of things. My only reason for saying that is IF your insurance company doesn't have a problem with it; in the event that you ever had a boating accident with an "over powered" boat, I'm about 99.99% positive that the lawyers would have a field day with it. So for 5-10 HP it wouldn't be worth it for me. |

| The guy whos selling it said he was inspected by the coast guard and the IDNR and nothing was said.
Also said when it was installed it wouldnt be an issue for 5 h.p.
ugh... what to do... |

and i looked up a 135 optimax and it weighs 23 pounds heavier than the newer four stroke, so weight wouldnt be an issue |

Location: NE Ohio | every time i've had a safety check done here in ohio they have always checked the HP rating on the boat plate and looked at the motor. just my experiences here. good luck.

If the boat was stolen or involved in some kind of accident on the road there would be no problems. The only kind of scenario I could see this being an issue is if the operator was involved in some kind of on the water accident and he is considered liable. Then being over the max HP would be a factor. Like another poster stated, lawyers would absolutely take issue with being over the maximum. All of us know it is a non-issue for weight and boat performance but over the limit is over the limit. |

Location: NE PA | You can get a new capacity plate made. You enter in your dimensions of your boat and it spits out capacities. Generally the manufacturer provides numbers that are a bit on the conservative side. My Jet boat was originally rated for 135hp (at the pump). After getting a new plate made the CG rated it for 165hp. I was able to mount a 160 optimax jet on the back (225 powerhead, 160hp at the pump), and couldn't be happier. No issues ever getting stopped other than some laughs by the fish commission when I run it in the winter with a helmet, and I am fully insured.

new plaque can be made here

Below is quoted from Tinboats.net
_______________________________________________________________
- This is to only be used as a guide.
- You can round your final HP number to the closest multiple of 5. (31 HP would round to 30 HP. 33 HP would round to 35 HP)
Step One - Compute your Factor
A. Length of Boat x Transom Width (measure in feet: 14, 15.5,16, etc).
Step Two - Compare your factor to H.P. rating
A. 0-35 = 3 hp
B. 36-39 = 5 hp
C. 40-42 = 7.5 hp
D. 43-45 = 10 hp
E. 46-52 = 15 hp
Step Three - If your factor is over 52 (Choose only A or B)
A. With Remote Steering (steering wheel) and at least 20" transom height
Maximum HP = (Your factor x 2) - 90
Example: 19' 6" long , 7 feet wide = (19.5 x 7 x 2) - 90 = 183 (Round up in multiples of 5. This boat's max is 185 hp).
B. With Tiller Steering (hand or extension) or less than 20" transom height (Choose only 1 or 2)
1. Flat bottom, or hard chined boats (hull has hard angles)
Max HP = (Your factor x 0.5) - 15
2. Soft chine, rounded hulls
Max HP = (Your factor x 0.8) - 25
I hope this has helped you all who are looking for max hp ratings. If your boat is insured, make sure to check with your insurance company for any restrictions.
This guide was found at NewBoatBuilders, which was ultimately used from "Title 33-Code of Federal Regulations-Subpart 183.53".

| I think thats only in PA though.
using that formula the number would be 145, if i did it correctly.
Dont see anything on the site where it says you can use the formula to have a new label made though..

Location: Already Gone | I wonder if a guy could get an engraver over to Dremel it in there...it wouldn't take much.
I have a 1890 Pro V that will get re-powered some day. It is rated for 190, I would like to put a 200 on it and call it even. |

| As a tiller boat owner I get all sorts of fired up about this stuff. My boat with a tiller max HP is 100. Put a steering wheel in the boat and it can magically handle 210 HP. I don't understand in the slightest. I have a UFlex non-powered hydraulic steering system on mine with a sticker stating 150HP max. Ever since installing that on my 90 merc I have dreamed about how to get a 150HP CG sticker for my boat that is fully legal so I can put a merc 150 4stroke on the back. No more boat dreams ever after that as it would then be my perfect rig. This stuff drives me crazy cause I could buy a boat that is 20' 1" and I bet the boat manufacturer would be happy to put a 150HP sticker on the boat when used with the exact steering system I have. I guess that 13" of length somehow makes the boat 60hp Safer?????
Just need to convince the CG that since the steering system actuator is at the end of the handle it should be considered remote steer  |

oh well, not sure why the guy just didnt drop a 115 on it...
Thanks for all the input again guys... |

| I have a tuffy rated for 60 tiller and I put a 90 on it with hydrolic tiller steering. The console version of the boat can hold a 135. If I were to do it again I would have went 115, as it is the same size as the 90. Go for it. So much nicer running 41 mph vs 29 mph. |
