Does this look right. Motor shaft height

[Nippissing]

Would like to start. Not good with subtleties but your advice has been great and I relly appreciate your help.

Could you please look at these pics and see if this motor is at the right hight an any advice is welcome.

It looks an inch or two low to me. You generally want the cav plate even or an inch above the keel. It looks like it'll work, but you'll get better performance by raising it a few holes. Try it how it is, and gradually increase the height until you are satisfied with the performance, or it blows out excessively in turns.

Agree with 95. Even with the keel is a starting point; raise it up 'til you get problems, then drop it back to where it worked. Less drag from less LU in the water.

3 inches too low

Thanks,

does it look like i can make it work with this motor?

[Nippissing]

Is it easy to lift the motor? is there proper lifting points on the motor? Im probably going to have to use the tree and the chainblock approach.

looks likes there maybe silicone or something between the plate and the transom.

hoping it just pull 4 bolts raise chaninblock and put bolts back in. maybe apply silicone if thats what it is.

Thanks for any comments

or maybe easier to use the trailer jack and a block of wood under the motor keel?

When you take the cowling off their will be a eye let to screw an eye into ( just like the front towing eye on a car) it will prob be in the middle of the fly wheel.
It's easy just time consuming.


Good luck.

The sealant is likely just caulk to keep saltwater from seeping in and crystallizing.

Agree with all of the above. My guess is you will end up raising it all the available holes.

Thanks everybody,

I have found out there is a compermise in setting up this boat. I raised the motor 2 bolt holes ie one from the last. I think its not bad but now this is as much trim up as i can get before the motor head hits the crossbar.

This might be the best i can do with this setup. Do you think the trim limitation will be a problem. I am hoping this will make a difference in the performance , water coming in the hull and the miliage.

Thanks again.

Holy cow!!! Rpms up to 5200. At approx 35mph. Before I chickened out approx 80percent throttle. Airborne in the chop. Wow. Thanks guys. Unbelievable difference. Moved up motor and new prop.

Find flat water and get a WOT rpm reading. That will get you an idea of the correct prop. Then you can (if it's worth the effort) start tweaking similar props to get teh best performance.

Or be like me, and live with what you've got.
