Recently i decided to bring my -2" Imco drives to Craig at Wilson Custom Marine. He was a pleasure to work with. I took the drives down to the key west worlds where he offered to store them in the Gieco trailer for me, and take them to his shop to be blueprinted. He also met me off I-95 when they were done to shorten my trip to pick them up. Once i got there to get them they were like a work of art. He took time to talk to me about the drives, and what he did, etc..

The results so far have been great. I have only been out testing 1 time since picking them up, but so far i have noticed about a 3 mph gain. I am only running low 90's, so that is a huge increase for me. Conditions were not ideal last weekend, as the current wanted to push one way, and a 10-15 knot wind the other way. With the right conditions im certain the boat has more left. I have also noticed better handling characteristics, and easier planing when running 1/2 cut diffuser ring props. Which was a big factor for me in doing the work, due to the handling of my boat and its given power.

The results and entire experience was well worth the time and money, i would recommend WCM for anyone who wants to go faster. Props, bottoms, drives, etc.. Props and Bottom work are next for me.

Boomer 35 what power do you have with props , I asume that your boat is non step, that is a great speed increase

.


Please send us pics of the reworked lowers

I hear they also do props and does set up for optimal drive location

is this only worth doing on boats that are fast 80+ mph?

Ttt

I have rebuilt 500EFI's. 32p 4 blade merc props. I have tried alot of props, herrings, 6 blades, 5blades, etc. But these seem to work best for me.

I cant answer too many of the other quesitons, i just wanted to post my results as there has been alot of talk and wonder on the blueprinting, with very OSO experience with the IMCO SC.

ill try to get a pic this weekend

Do you have a phone # and location for WCM? Thanks Bob

Craig is in my shop as we speak, here is his # (772) 285 3562.
