I’m in Southern Idaho Frank. The trim tabs cured my porpoise issue and helped the list some. I adjusted them last night. They were set the same on both sides. I’m optimistic the adjustment will help. Wont be able to get her out until maybe Saturday. I’m seriously considering a 17 pitch 4 blade prop though. I also see a lot of boats with hydro foils on them (whale tale) I’m curious what one of those would do.

That’s a good idea. I think I’ll mess with the adjustment. I’m thinking as high as the tabs will go starboard and as low as they will go port. They are even now.

We’ve measured and checked. It seems to be mounted square. I haven’t lasered it or anything.

Thanks for the response. I’m convinced my 18 Pro has too much engine. It came with the 150 Yamaha 4 stroke. I left it with the dealer the whole month of June. They stopped making excuses after they ran it. They installed manual trim tabs which seem to have cured the porpoise problem but I’m still listing port side. It sits level in the water not under power. My pilot son in law thinks it’s prop torque. The dealer shifted all the weight possible starboard but it still lists under power. I’m considering a different prop. Maybe a 4 blade? I’m running a “solas” stainless 3 blade 14″ 19 pitch now. It really sucks having a new boat you’re not in love with. My dealer is two hours away so I’m fed up hauling it back and forth.

I just messaged Frank Slover. Hopefully he found an easy solution. My boat is back with the dealer now. They are going to take it out and see what it’s doing. I feel like they might think I’m exaggerating.

These posts are a year old. I’m hoping someone has found a resolution to the Starweld listing issue. I wish I’d read this forum before taking the plunge. I recently bought a Starweld 18pro with a 150 Yamaha 4 stroke. Under any power it leans slightly port side. However at 3/4 to full throttle in leans hard port side. It seems like a torque issue. As you throttle down it tips on its side simultaneously? AS far as weight distro with me driving it by all means should lean the other way? Any of you previously discussing this problem find a fix? Mine is back at the dealer again they seem perplexed as well. ALso. As it leans port side it also starts to porpoise. Its actually pretty scary. You have to shut it down to come out of it. The dealer has already shimmed the engine due to porpoise issue at all speeds. That helped at lower speeds but don’t dare open it up.
