question on a 27 Fountain
 

A friend of mine has a 27 Fountain (no step) with a N/A 540 in it. He really never dialed the boat in last year and his best speed was 79.8 gps.

Well this year he is doing some testing on a drive that a friend built . Bravo /XR conversion with a Imco nosecone. Well the problem is the boat won't run anything over 75 and he says it likes to blow the prop out when he corners.
It is running the same rpm (5700) as last year...were did the speed go ?
Do nosecones not work well with Fountains ?
I'm ruling out the XR gears slowing it down because I put some time on that drive and I think the nosecone actually helped me.
He's just very frustrated and plans on pulling the motor out next week to change the cam and do some welding and porting on the heads (airflow technician for a living)
Any ideas ?

Here's the thread I was talking about in the General Forum yesterday. Its about a nosecone on a 29 Fountain. The 29 and 27 Fountains are similar. If no one replies to this thread maybe you can email the people who posted on the thread about the 29.

Hope this helps,

That's my boat. I posted a response on the General Discussion section. I'm hoping to find a way to take my nose cone off, because I don't think it's helping any.

Just started testing after switching to an XR drive. My guess is that we lost 1 or 2 mph. Any one else with XR swap experience?
