Location: Tinley Park, IL | So maybe someone on here can help my out.
Yesterday was my first day on my X-190 (Yamaha F175) with a full load and I had some major issues with the boat's performance. I have had the boat since May and I have been very pleased with the performance but that was always with just a single fisherman and an empty livewell. Yesterday I had a second angler (275 lb guy) , his 75 lb tackle bag, and a full livewell.
With the extra weight, the boat took 5-7 seconds to get on plane. With my normal load it always just pops right up. The other problem was the terrible porpoising. There was a lot of boat traffic and lot of big wakes coming from all angles.
I don't know where to start with this. Is it a prop issue? I have a 3 blade, 19 pitch prop. I played around the trim when the boat was porpoising and that helped at times but at speeds of 25-35 mi/hr which is what I wanted to run with all the boat traffic, it was a major issue. When I accelerate faster the porpoising subsides but I don't want to hit large wakes at 40 mi/hr. Any input is appreciated.

| If you are normally driving faster and then the traffic made you yield speed you must operate the trim less or lower.
My boat will run at full trim all day at wide open however the slower I go the most if must be. At 22 mph it is all the way down.
Holeshot, that's just what it is going to be

I forgot. Do you have a X-190? |

Location: MN | Maybe get some recommendations on a four blade? You may lose a little top end, but you will have a better hole shot and potentially better handling too. |

| I'm no mechanic and I didn't stay at a Holiday Inn Express last night, but....
I think you have plenty of power. Some of your issues, especially with the boat getting on plane may have been weight dispersement. And probably will be what it will be. Maybe the 75 lb bag on the deck would have helped matters.
Now the porpoising? That's gonna happen a little when you are getting hit by all angles and trying to stay on plane. As suggested, keep your motor trimmed down and "plow" the water if you want to go slower as you were doing. That will help. And, common sense, try to hit as many waves head on as you can.
I don't think it is a prop thing, or a boat thing. I think you just had a heavy load, lots of wakes to deal with and boating traffic that made you run the boat at a slower speed.
I seriously wouldn't worry about it. I've got a 619 with a 225. Had similar issues on Sunday late morning when tons of boats were on the lake. Tried getting it on plane and trimmed up, but was just getting rocked by those wake board boats wakes. Trimmed her down, plowed where I could and the ride got better. It happens.

Location: Rhinelander, Wisconsin | It's propping as far as the hole shot, and that's a compromise depending on load and weight distribution.
The rest is trim related as a primary and prop as a secondary, and from the sound of it, conditions. The above posts have good merit.
Contact your dealer to discuss performance and load, and to look into propping to match your needs, and your Tuffy rep for additional assistance to make sure it's set up for your intended use.

The more I thought about it, the holeshot was due to the livewell being filled. At takeoff my holeshot was fine and there was no porpoising until later in the day with boat wakes.
