I suspect that the torque (acceleration) vs HP (speed) thing is less useful for boats, so that one would miss any horsepower that weren't there. Don't small boats spend a whole lot of their time at or near top speed? > gas motor would run ~ 4 to 5K rpm at or close to full throttle. Mine does.

On my boat that was done with prop selection. The pitch of the prop is in effect the final 'road gear'. I got both carburetors off my motor. No sign of gunk in them in spite of not having run since '91. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
