" I have a 16 ft. sportline cl

" I have a 16 ft. sportline closed bow boat with a 75hp evinrude starflite 3 V-4. Model #50524 AND SERIAL 03096. When i first get into my boat it starts right up , but after fishing for a little while the motor is very hard to start again. Sometimes it will not start at all after the first time. when the boat is running it is very strong and runs well. Sometimes if i let the motor sit for an hour or two it will start. any suggestions would be great. I do know about motors just not boat motors. "

"Mike.... Your engine is a 196

"Mike.... Your engine is a 1961 75hp V/4 Evinrude. The problem you state could be caused by:

1 - A faulty carburetor float level. Remove the hood and look straight down the carburetor throats when pumping the fuel primer bulb. If you see fuel flowing down into the engine, the carburetor needs reworking. After running, especially should a condition exist where pressure could build up in the tank, excessive fuel would flow into the engine and in effect flood it with fuel. If the carburetor is okay, you might have a problem (when the engine is sitting) where fuel is draining back into the tank... if so, try pumping the primer bulb again before trying to restart.

2 - Within the distributor cap, whether you have a magneto or automotive ignition, there is a rotor. The automotive rotor has a straight edge tip on the end of it such as you would normally see on a automobile distributor. The magneto rotor tip has a hook like appearance to it. The two are not interchangable. These rotors, especially the magneto rotor have been known to intermitently crack open slightly at their base and short out to the metal shaft that retains them and the rotor fails, effectively shorting out the ignition. When they cool off, the crack closes up and the ignition returns. In time of course, the rotor will fail completely. The OMC part numbers for the rotors are:

Magneto Type Rotor=#580260
Automotive Ignition Type Rotor=#580338

You may have other troubles such as a failing coil but the above is the most likely problem. Should you need a rotor and have trouble finding one, contact me via e-mail (Click on my user name in the blue heading above).
