Just wanted to add a little update for those who have the same issue. Took the boat out today and played with the trim a bit and different speeds and I can get the boat to plane when going a little slower, gonna talk to my local prop shop and see if they suggest cupping this prop or if I should change props as I need a couple hundred more rpm and a little more lift.

So I couldn’t find any dull spots on the prop, also checked the prop to pad measurement and it’s 3.75” below the pad if that helps

That all makes a lot of sense. Thank you for the info! The only reason the batteries are moved up a bit is because the local marina recommended that for my planing issue saying I was to heavy in the rear and needed to balance it out a bit more. Even before I moved the batteries it was doing the same thing. If anything moving the batteries slightly helped but not enough! I’ll do a little investigating today and get my prop to pad measurement and go from there and check for signs of cavitation as you stated earlier.

I’ll definitely take a look at that tomorrow, the motor sits extremely low. The jack plate was mounted on the lowest setting and the motor is mounted to the jack plate on the lowest setting too. So I can’t imagine it would be getting air but I’m no expert so you could be right. I guess I’m just not sure when to stop trimming up when trying to plane as well. I eventually get to a point when the motor sounds a little bit louder and sounds like a droning sound. I never really push it past that because I don’t want to ruin something and I’m usually full throttle and the more I trim the higher the rpm. Wonder if I have to pull the throttle back a bit, trim up, then add more throttle. I’ll admit I’m still new to boating so I’m certainly not a pro at planing boats to begin with. Not too mention this one has a jack plate as well so there’s that to play with too. I’ve only had experience with one boat prior to this.

Yeah you could be totally right, may honestly be all she’s got. Saw a G3 1910 LE at my local fishing hole the other day and the guy had a Yamaha 150 on the back and man was he moving! Those boats are gorgeous!

Yeah believe it or not, 22P and over revs to I’d say 5900rpm or so. That’s with full tank of fuel (21G) lots of fishing gear and 2 220lb guys, and we hit 35mph but plowing water. I’ve had the boat for a year or so and has never planed since I’ve had it. To my knowledge it’s still a 90HP unless someone got the computer flashed to a 115HP before I bought it, not sure how I could tell. The prop has the PVS plugs and I have 2 out and the hole shot is great but once the bow drops I try to trim and it has a hard time lifting the bow and doesn’t plane, just plows. I’ve had a 1988 Bass Tracker tx17 with a classic fifty in the past and I used to plane that out no issues. I saw in a previous forum someone said a PT190 with a 23P Trophy Plus is the best set up but then you see others running 18P. Not sure what the big determining factor in prop size is here. The only way I would think the prop hub kit could be slipping if maybe it’s the wrong one but I would think I wouldn’t be able to hit 35mph if that was the case. Not sure though??

To start the boat is a 2007 Bass Tracker PT190. It’s equipped with 3 batteries (2 of which are in a compartment mid boat/bow area), 2 10ft power poles, 6” Atlas Jack plate, and a 90hp optimax 2stroke. The boat used to have an 18 pitch vengeance prop which would cause the boat to over rev like crazy. Eventually I bought a 22 pitch Laser II, the rpms seem to be more in the ball park but once trimming when trying to plane it eventually starts to rev past the limiter (5800rpm). No matter what I do it feels it still wants to plow water. Could my engine be sitting to low not allowing it to plane? Do I possibly need to raise the jack plate after hole shotting and before trying to trim up? Can my current prop be cupped to lower the rpms a bit? Would a 4 blade prop work? Was thinking about investing in a 23P Trophy Plus if that would cure the issues. If anyone’s got any ideas they would be much appreciated. Any questions that need to be answered just let me know!
