I have a Chrysler 135 with a 13X21 prop on a<br />1974 Beecraft 16' tri-hull. the problem I'm <br />having is the engine won't make operating rpm<br />of 4500-5500 rpm, I get 3800 rpm @ 30 mph <br />with 2 people in the boat, and with more than <br />2 poeple the boat won't even get on plane.<br /><br />The engine starts well and seem to run well<br />comperssions are 120 to 125 ps1.<br />jets are .096 <br />my altitude here is 3500 above sea level<br /><br />Is this to much prop or could the jets be to large? Any help is appriciated.
