    Engine recommended RPM

    Hi, Does anyone know what the recommended crusing RPM should be on 270 Crusaders,<br />in a 31' 1987 Silverton. I normallr run 3000 to 3200 is this too much or too little. I have 20x18 props on 1&1/4" Shafts running out of V-Drives.

    Anti freeze leaking

    I Just replaced the heads on my Crusader 270<br />(1987) vintage, Seems I have a slight coolant leak from the exhaust manifold. The bolts seem short 5" long 3/8 16x5 looks like only a half inch goes into head, & they strip easy. Does this sound strange? How do I correct this?
