Merc '94, 40 HP ELPTO, Max RPM's?

Thanks! That's exactly what I needed.

I have a 55 gallon barrel that I can use for the stress test. First I'm going to veirfy the mixture at a moderate setting. Then I'll adjust the max RPM blocks.

The boat is an '83 Starcraft SSC 150. That's a tin, split console, run-about. I think the boat did better than I did. I made a few newbie handling errors but after an hour it was all coming back to me.

Kamper, make sure that drum is anchored in place (ie:cornerered in garage with boat backed up "tight" and a constant water supply)..40hp at WOT with a prop (not a test wheel) is a mighty powerful thing...when was the last time you ran some Sea Foam through it.?..happy tuning..

Oh yeah. I've used the drum before. Slip it empty over the drive, straighten out the l/u to vertical, fill the drum at least half-way. That's 200 lb.s. It has never moved. I tape a hose over the pisser to recycle that water too.

I changed-out the water jacket and exhaust gaskets before storing it 2 years ago. No build-ups to worry about. I rebuilt the carbs at the same time, too.
