Nosecone

[filthy phill]

it realy looks like a factory gearcase now.
it realy is a good looking job you have done.
you need to take a mould from it and make a few alloy nosecones or fibreglass cones, maybe even hard plastic ,
they would sell for sure.
nobody out there making nice cones to fit straight onto a omc 56 big gearcase.

L/u works great! Have it 2cm higher than before and boat was easier to drive, goes allmost neutral trim, with 2 its neutral and prop torque is way less than lower setup. And there is waterpressure all time except when when its all airborn. And best of all, dont need to drill anything on the transom!

Best mod ever with lifting strakes lenghtened on the bottom👌.

Have to try even higher.

[filthy phill]

good that its working like you want it too.
And good that it is holding up to high speed runs and not coming off.
have you thought about putting a torque tab on the bottom of the skeg being as it is running so high now ?

[filthy phill]

why did you make exhaust deflectors longer ?
is there a reason for this ?

[hupiveneilija]

Sound, its more quiet now. Softer sound.

[filthy phill]

ahh I see, that makes good sense.

hupiveneilija, That's some really nice work you're doing, straight as can be & cleanly feathered. I'm glad you are getting desired results.

[hupiveneilija]

Thanks!
Worked real fine. Last saturday was very ruff but didnt lose water pressure not a single time despite running propshaft near inch over bottom.

[filthy phill]

Well it proves the low water pick up is working perfect if props hat is 1 inch above bottom of transom.
Plus it is also running on the cone good.
Definitely looks very good. Wish I could make one that good.

They really do work well, vulnerable only to clogging or running too slow & slow doesn't even count when you're running a pump. On height, the higher the better to a point, then control & traction diminish while speed doesn't increase anymore. Just right for your needs is what counts, if you want to turn well too high can be troublesome. To measure for being symmetric I made a wood gauge that clamps to the prop shaft & protrudes forward. It's being parallel to the shaft makes it easy to measure in from any point except where the devise hits the gear case & fin. I was surprised to find how off-center a few gear cases were.
