"Hey guys, thanks for your hel
"Hey guys, thanks for your help in advance. My question is do you think a wrong propeller size 14X21 on an '87 17 ft. Sunbird with a 3.0 merc. and alpha 1 could blow the head gasket? I have not been able to get my rpm's past 3800 with a speed of about 30. Also, while out 2 weeks ago I was idleing in shallow water and hit a rock causing the motor to stop and bend one blade on prop. I wouldn't think this would be the cause. I think wot rpm's should be between 4000 and 4500. The temp. has looked ok, don't think it overheated. No water in oil. Thanks again."
