Mercruiser 888 starting problem

I have a '73 Fiberform 19ft runabout. The engine is a Ford 302. I can jump start the engine from the solenoid, but I can't start it from the ignition switch. When I turn the key, the guages work, the trim works, but I don't even get a click from solenoid. I've cleaned the battery terminals and made sure they are secure. What can I do to solve the problem?

Re: Mercruiser 888 starting problem

is it in neuteral ? if it is, neutral safty switch may not be working. stern drive or inboard?

Re: Mercruiser 888 starting problem

does it have a dead man switch?

Re: Mercruiser 888 starting problem

One of these:<br /><br />1) Ignition switch is faulty<br />2) Neutral interlock in your throttle/shift control is faulty(you sure you have it in neutral?)<br />3) Wires between ignition switch and neutral interlock or between neutral interlock and starter solenoid are open.

Re: Mercruiser 888 starting problem

Yup, its a Ford. (I'm a big Ford fan and have an 888). I suspect you need to replace the solenoid. I have yet to own an older Ford that didn't eat at least one of those, except my 888, but I expect it at any time. I dread it to since the solenoid on mine requires a contortionist to change out. It's an inexpensive part though.

Re: Mercruiser 888 starting problem

Thanks for the input. In reference to the questions: It is a stern drive, there is no dead man switch, I checked the ignition switch (OK), it's definately in neutral, I'll check the wires between the ignition and solenoid. Is there a quick test to check the solenoid?

Re: Mercruiser 888 starting problem

Just because it's in neutral dooesn't mean the neutral interlock switch is working correctly. You need to get your meter out and start checking things.

Re: Mercruiser 888 starting problem

My solenoid test has always been if I can short the posts and get it to turn over, or on must Ford solenoides I've had die, I could tap them a few times with the end of a screwdriver and get it to work one/two more times. If it were automotive, its $7 bucks at autozone, the marine version is probably no more than $25. <br /><br />I guess you could always use a meter on the starter post to see if current flows when you turn the switch or to see if the field wire has power.<br /><br />I usually don't spend much time testing them. If they are suspect and I can bypass them and get action, I replace. Used to have a car that went through one/yr like clockwork. It has to be a Ford thing. Last time I sat one on the counter at the parts store, the guy looked at it..."Ford, huh?". "Yup".

Re: Mercruiser 888 starting problem

Check the motor kill switch. 888s have a switch to kill engine while shifting (takes engine pressure off gears). Wires to mine touched and melted on exhausst manifold. Engine was dead as a doornail.
