Nosecone

The nose cone came out great. What is the purpose of the spacer at the prop? Is it suppose to send the exhaust out of the holes you added to the gear case?

Very funny.
It's there to help a over hub prop when pulling away
You can buy plastic ones but they fall off..
Large holes in gear case aid in better intake for water rather than needing low water pick up.
This bloke is getting 26psi water pressure with bullet just above bottom of transom. So it works perfect.

Like this engine height water pres.1,5bar

[filthy phill]

that is still almost 22 psi so should still be very good.

what pressure did you get before on normal gearcase ?

and what propeller is that on the engine now, it looks a good one.

[hupiveneilija]

If i remember correct it was 1.3bar with transom p/u.
Its a 18inc raker.

ahh so you now have a bit more water pressure than with transom pick up, that is realy good. makes it a nice neat project to do.
only problem I can see is there is no Gauze/filter material inside the large holes !!!
I would prefer to have a gauze or filter and I have some material that would be ideal for this, would not want something like plastic bag getting sucked in the
large water inlet and destroying water pump or stopping flow.

I like the exhaust deflectors, they look very good, definitely a nice extra touch.

This works like I was hoping it would. With this height dont need extra pickup. Go up from this and pressure drops a little before needle starts wondering up and down, so higher setup will need extra pickup for water.
What comes to that ring in front of prop and those exhaust holes above A/V plate, they make takeoff really easy. Foot down, nose up, when it comes down revs go up , ease on throttle.
VOILA' 20kn on plane, no hassle.
