Left side lean?

[Ground Pounder]

Hello troop's, I purchased a 2003 Aqua Sport 175 CC, w/h a 115 Suzuki 4 stroke, the boat and engine have less than 300 hours run time on them, she's pretty much a very new combo, here's the issue I'm having, at speed she has a pretty hard lean to the left, I've tried the hydro foil on the engine, no luck, I have installed a set of automatic "Trim" tab's, NOPE! Neither have brought the boat to run true and flat at speed. I'm out of option's? Side note, I'm not a boat guy, I'm a retired mechanic so working on equipment is a non-issue, any ideas on the hard lean?

Get manual trim tabs.

Get manual trim tabs.

Thank's for the reply, I was trying to avoid that but it's looking like that is the way to go, it's a small boat in my mind for manual trim tabs, I'll look into them anyway,

Yes she does, it's not a load issue, everything is normal except at speed, I've even changed the prop, was a 14x19 went to a 14x17.

While this may sound dumb, I have saw it many times.....is the motor hanging off the transom correctly ? Have saw a few that hang at an angle, or the transom cutout was not parallel to the bottom if the hull, especially on glassers. Another issue could be a dent ( hook) in the hull causing a list when on plane. Mabry some videos to help us see your issue...good luck

No old equal and opposite reaction at work

The clockwise rotation of the prop forces the boat to lean left. They all do it.

Manual trims tabs will resolve the issue

Thank's for the help all, I went ahead and ordered a set of manual tabs, I'll post after I install and test.

" I'm not a boat guy"

I'm responding based on this.
Do you mean "leaning" or "turning".
Some outboards have an adjustable trimming tab on the lower unit that's also an anode. This trimming/anode tab is used to straighten the boat, if needed, at speed once properly trimmed.

Also, you change props to keep engine rpm's in the manufacturers specified rpm @ WOT (wide open throttle) , not to correct an untrimmed situation.
