Proper Prop poser

[closerhauled]

Just bought an '83 Evenrude 35 horse with remote steering attempting to push a '16 Pacific Mariner fishing boat. It only gets it to about 7 MPH; doesn't plane. Motor starts and runs well. At that rate the fish are faster than I am. The prop appears to be a 10 x 15. I just bought the boat/motor. Former owner said went about 24 MPH for him. Is the prop the wrong pitch? Is motor too small? Did I get the shaft? Rookie Salmon chaser needs to know! <br /><br />Thanx in advance...

Howdy, Closerhauled.<br /><br />To begin to answer your question we need to know what rpm the engine is reaching. It would also help to have an idea of what your boat weighs.<br /><br />Among the possibilities are:<br /><br />The engine is only running on one cyl. in spite of "sounding" okay.<br /><br />You have a spun hub on your prop.<br /><br />Your prop is too short in pitch.<br /><br />Your boat is too heavy for your engine.<br /><br />Either the carb or the ignition, or both are not reaching wide open position.<br /><br />If your seller was telling the truth (not at all guaranteed) the most likely is that your engine has dropped a cylinder. More likely, your seller withheld important information from you.<br /><br />Let us know.
