Thanks guys. I am making plans to order the IMCO SC. It’s a little scary when your the first to try a new setup on a 26. Not sure if I need the -3 or the -2. I plan to make more precise measurements on the X dimension tonight.

Thank you all for your suggestions. I just ordered the SC Extreme upper and lower package with the -2 lower. This should place the X at 5.25". I will report back on any changes good or bad.

woulnt it be better two get the -3 shorty,,,,and if dosent work you can start spacing down

RPM's were at 4700. Too much prop and the X is too deep at 7".

there was a 05 25ol that had a 525 and he installed a 3'' imco box 3'' is a built in raise box is 12'' he went from 74 to 81 with a b1 28, he then installed a merc 600 plus a 2'' shortie and ended up putting a 1'' spacer which gave him a height of 3 1/2'' last I heard he was at 87 to 89. if you go to 600hp you should change your gears to 1.50. the 1.65 lets you use a 26 other wise you would of got a m23
or b122 with a 1.50 gear. that you can get with the case, I noticed you lost some angle with the shorter exhaust hose since you did not get the extentions watch out if you change your cam you could suck water back up the hose at idle. looks great my project is on hold my engine builder sleeping on my 572 blower motor for my saber28:evilb: but Iwill have it in 2 weeks so we will be posting over saber about the install with the konrad ace drive. good luck my baja flew straighter across rough water with the shortie. |
There are guys who have put the -3" IMCO lower on a Bravo upper. They cut the cavitation plate off. Not pretty, but it works.
I remember they bolted a cav. plate back on, but spaced it up with what looked to be 1/4" tall spacers. |
