motor height ?

bullet175 · 10-19-2008, 11:42 PM

At full plane WOT this is where the water level is at the gearcase of my motor. Seems too low to me as the gearcase bolts are in the water at this height as well the cavitation plate is below the waterline.

I still have one bolt hole left on the mount to raise the motor.

With the plate mounted at the same level as the bottom of the boat, the waterline might be higher then where you have it marked. Is the plate (red line)at the same level as the bottom of your boat?

I would think it's suppose to be up to the next line.. 3-4inchs up... what type of boat and motor?

No I know it shouldnt be that high. Its a pro line 20 sport with a honda 130.

Tuna Man's got it. The only draw back sometimes is, depending on the hull of the boat, you may loose some trimming ability and may have blow outs in turns. It doesn't take much to try and see if you like it. If not, put it back. Make sure you use silicone to seal around the bolts.

I would leave it where it is.

I raised mine up like that, so that the cavitation plate was level with the bottom of the boat and when I would turn moderately it would cavitate/suck air and lose thrust. I ended up having to lower mine back down to the original location.

If it's just a couple inches , I'd leave it where it is....

While what BIGRIGZ said can happen, if you trim the motor down in a hard turn it helps and is how race boats are run.

As DOUBLE "D" & LV said different hulls react differently. The anticavation plate can be level with the bottom of the hull or sometimes even higher.

Your RPM will increase when raising a motor and your fuel millage may increase also. These are some of the benefits of raising a motor.

I raised the motor to the last hole left in the mount and yes now the cav. plate is even with the bottom of the boat. I knew it didnt look right when I looked back there while we were running the boat. But I guess the idea applies the same to these as they do to bass boats. Just wasnt sure. Needed some confermation. Thanks for the help everyone.
