POLLIWOGG Posted May 23, 2007 Report Share Posted May 23, 2007 Look in your manual for W. O.T. wide open throttle. Probably around 4500 Link to comment Share on other sites More sharing options...
Roy Posted May 23, 2007 Report Share Posted May 23, 2007 You sure it's a 2L ? Link to comment Share on other sites More sharing options...
Fisherman Posted May 24, 2007 Report Share Posted May 24, 2007 Not 100% sure but they list a 3.0 Litre at 44-4800 rpm, and it's an inline 4. Quite a few years back somone rplaced a Volvo Penta with one of Mercruiser series, I do believe it was a 2.2 ror 2.4 litre GM block. Link to comment Share on other sites More sharing options...

lilkynan Posted May 24, 2007 Author Report Share Posted May 24, 2007 Thanks Ian - turns out with my 3 liter - 4400 - 4800 is peak and top range - only had her at 4000 on Monday and hit 40 mph - so will bring her up to 4800 this weekend if smooth and see what happens. Thanks all Link to comment Share on other sites More sharing options...
Uncle Buck Posted May 24, 2007 Report Share Posted May 24, 2007 your boat should be proped so that they max RPM is at WOT, any more (over-reving) and you could be doing damage, any less and you're loosing max power... Link to comment Share on other sites More sharing options...
