+3 on the additional info needed on the twin turbo setup. post some pics lee!

are you running a mercruiser 1 drive? how fast are you going with the turbos? what prop?

i'm at 55mph on the gps. not fast by off shore standards but clipping pretty good for a boat meant to go 30mph and only 18' in length.

ps. your searay looks really clean!

I cant believe the vinyl next to them turbos doesnt melt !!!! (sweet setup tho)

It's a mild 351W +10-12lbs boost, spins a 23p Mirage thru 1.32:1 drive to 6000, still has throttle left but it is a real handful and did not want to rpm the engine any higher.
This winter going to change to a -2 shorty with 1.5:1 and a 28p-30p prop, and dual hydraulic steering.
Boat is all original including the interior.
The vinyl cushion on the left side does not usually touch the water jacketed housings which only get slightly warm, it just slid over when the engine cover was pulled back.

So that thing is running around 85 mph??? Holy ****! Awesome sleeper dude!

No, I think it has a lot of prop slip.

how fast are you running lee?

Don't know, as it is currently with the small prop and a lot of torque steer maybe 70, after the changes this winter I will get it dialed in and let you know.

Man, this thing would make some of the "fast" outboards, jet boats, and offshores around my neck of the woods pretty butthurt, haha. So awesome.
Got any video clips of it running? I bet it sounds great.

still for sale!!!

Hey 88 ive been busting your balls over selling that, but in all seriousness you've got the big c.i. Why not just slap a big blower on it and gain 10 or more mph if thats what your hunting for?
its a Sweet 28
