Hard start revisit.......

I've been here before about this issue. I have a 1992 Bayliner Capri with the 5.0 Mercruiser alpha I Gen II.

Starting it on the muffs is usually fine, no issues. After trailering to the launch and getting it in the water it will give me a hard time starting. Usually have to pull the engine cover and crank a few times to get it started.... Now that I write this I realized that when I'm at home on the muffs the engine cover is off....hmmm, anyway (The choke coil (whatever it may be called) gets hot so I have disconnected it and wired the choke open, I know that is not correct, but still it starts okay on the muffs this way so I'm assuming that putting it in the water wouldn't change the choke.)

I think it was in one of my past threads.....someone said about when it's in the water and the water is up in the exhaust that it changes everything and timing is usually the issue. I have the timing set to where it's supposed to be. I don't recall what that is, I think it was 10 or 5 BTDC. I set it using my Timing light.

What I'm asking is for some tips on this. What can I try and / or look for when I'm at the dock or on the water somewhere and it's giving me a hard time starting?

I have cleaned the arrestor so that is not clogged or even dirty, but it does seem to start better with the arrestor off. Even though its clean and I can see light thru it should it be replaced with a different / better one? Could that be part of my issue?

Engine has new plugs, cap, rotor, wires, fuel separator filter. I run standard 87 octane gas.

Thanks
Dave

Re: Hard start revisit.......

Are you just leaving the throttle in neutral and at idle when starting?

Don, I usually prime it by giving it one or two squirts from the Throttle, but then yes I believe I usually put it back in Neutral to crank it. I say I believe I do that because I haven't even started it this season yet so I'm asking this question ahead of time.

Re: Hard start revisit.......

Don, after reading what you said and thinking about it.... I'm thinking I need to use some throttle due to water pressure in the exhaust?

Re: Hard start revisit.......

Give it some throttle until it warms up. It's a carb, not fuel injection.
Warming up for a couple of minutes at 1000 to 1500 rpm will make life much easier.

thanks Don.....I should be on the water this weekend and I'll give it a shot. I'll post back.

Thanks
