V-6 150 starting issues... starter disengages too early

Hi. My '79 V-6 150 will crank and crank and then just as it starts to catch, the starter kickes out prematurely. If I give it a second, then crank it again it stats to crank and then kicks out again. Eventually, with enough cranking it finally starts, but seems like it would be easier if it just cranked a second or two longer before disengaging the starter. When it disengages, you can hear it spin freely. Also, if you don't give it a full second or two between attempts it will just spin freely without engaging.

Any ideas?

Thanks,
Dennis

sounds like u need a tune up
when was the last time u did that and a de-carb?
are u using the cold starting sequences in the manual?

Thanks for the input, I'll try that. It's funny, it will crank forever and then kick out just as the motor begins to catch and want to start.

Thanks,
Dennis

A weak battery will also cause this. Make sure its fully charged and you might even have it load tested. Your starting procedure may be part of the problem as well. When the engine initially fires (even though it doesn't actually start), its sudden pickup in cranking speed overruns the starter and kicks out the bendix. Its designed to do that. On cold starts, raise the fast idle lever, push in on turn the key and hold it in while cranking. Cold engines need a little extra throttle and lots of choke. If this problem occurs at idle it may be the idle speed is set a tad low. You can again verify that by simply raising the fast idle lever when starting.

Mine always did that. Lubing the Bendix helped a bit, but the cure is just to give it a little more throttle on cold starts so that it stays running after it fires and disengages the starter.

Thanks for the help. I saw in some posts that I searched where the battery was mentioned also. I'm ruling that out because it's brand new and fresh off the charger. Maybe my cold starting methods just need some attention. I've been turning the idle up for the starts and using the choke for the duration. Partial throttle doesn't seem to do it. Maybe I have the linkage adjusted impropperly. Starting with that much throttle on my Evinrude will sound like it's going to blow if I was to go that far. My controls don't have the seperate idle lever like on my other boat, just the button to push in to disengage the shifting all the same. I also heard that these like to start with a ton of fuel. Maybe a few more squeezes of the primer bulb? I'll try a little lube on the bendix too.

Thanks again,
Dennis

Carbed engines need some throttle on cold starts -- period! It does not have to be full open. Next, make sure the primer bulb is squeezed until firm. Turn the key ON (not start). Push in on the key and hold it for a count of 8 to 10. Now turn to START. When the engine fires pull the throttle back to an idle speed fast enough to keep from stalling. If the engine begins to die off quickly PUSH the key in to give it a little more fuel. You may need to do that a time or two until the engine warms a bit. People are so used to their fuel injected cars that they have forgotten (or never knew) about chokes and throttles. Give it some fuel and throttle -- it will start.

I appreciate that. I guess it just comes down to learning exactly what this motor likes. Every carbed thing I own (other outboard, motorcycle, both snowmobiles) seems to have its own preference for choke and idle. This one just confuses me a bit because of its thirst for fuel on the starts.

Silvertip- I appreciate your info on holding the choke in for that time period while not yet cranking. That was something I wasn't doing.

Thanks

Hello

I had the same problem with my 115 I6, but as I learned her to know, I found that 10 seconds of priming (holding in the key) before I turn to start is to much. It is enough with 5 secs, the clue is to hold the key while cranking, and a little while after she fires up. And a lot of trottle... All the way on my idle trottle lever - which means about 3/4 of full.

when you push the button in to release the shift, the neutral stop will keep you from throwing it to wot when you move the lever forward.
