Boat Takes 1 Hour to Start!

Re: Boat Takes 1 Hour to Start!

Somehow this thread reminds me of the guy that claimed he could only start his engine at low tide, at high tide the back-pressure got too much!!!
You claim it always start easily on muffs with no back pressure?
If so:
1: Your starter/craning speed is too low?
2: Your exhaust relief holes may be under water?
3: You may have a compression issue on one or more cylinder(s) ?

Yeah Haffiman, it starts immediately in the driveway!

Starting procedure: I trim the motor down till it's level with the horizon. I pump the ball till it's hard. I put the key in the ignition & raise the fast idle lever. I turn the key to the run position and it beeps. I press the key in for 5-7 seconds, then whilst still pressing it in I turn it all the way to the clockwise & crank the engine. If it fires I stop pressing the key in. I have confirmed the primer solenoid works by running the engine & pressing the key in & it bogs down...

Do the following:
Trim down, but be sure the exhaust relief holes at the back of the leg are ABOVE water.
Pump up the primer bulb, turn the key to 'IGN' (beeeep), press the key in 3 times.
Idle lever in half to full position.
Crank (without holding key IN)
If engines fires, shortly press the key in to prevent from stopping, but not hold it in!!
Try to keep the engine running at around 12rpm during warm-up.

Are you relasing the key or does it just stop cranking?

1. Low compression. That's it, final answer.

When on the muffs without any back pressure it low compression is still adequate to push the excess fuel out the exhaust. When its in the water, the back pressure is present and holds too much fuel in the cylinder creating a flooded condition. After 58 minutes of cranking, the friction from doing that along with an occasion cylinder fire has raised the cylinder temps enough to evaporate off the excess fuel. Once that happens the plug clears and the spark gap returns which allows it to ignite the overly rich fuel mixture.

If you don't believe this then next time out. After you've had it running shut it down for three hours and when your try to restart it, pump the bulb and hit the choke. I'd bet your back to cranking for 58 minutes again.

If you disconnect the spark plug wires will it keep spining over ??

Re: Boat Takes 1 Hour to Start!

as mentioned in the other post on the same subject......it appears as tho you have a starter issue, the gear should not drop out like it is doing. maybe after trying for 45 mins, things relating to the starter are getting warm , then finally it keeps the gear engaged for enough revolutions to start the motor.

Re: Boat Takes 1 Hour to Start!

My brothers would do that,took forever to start.As soon as it fired one time the bendix would drop right down.I rebuilt all three carbs on his and did a sink and link,it started perfect then I went after the timing. She's a great runner now!

Re: Boat Takes 1 Hour to Start!

My compression checked out fine last fall.
& yes, the starter will stay engaged with the spark plugs out.
I pulled the plugs today and they were clean. I cranked it a couple of times and very little gas sprayed out. I will probably have the compression check again when I find a mechanic in Gallatin that won't rape me.
I'm just guessing that either,
1. My floats are set too high & I need a Carb Rebuild 2. My Quick Start Feature is advancing the timing too far on cold starts 3. Starter is malfunctioning.

Re: Boat Takes 1 Hour to Start!

By watching your video, I would guess you need a proper Link N Sink. The adjustments looked skewed.

Try cranking with the lanyard kill switch on. If it cranks without kicking out the drive gear, I'd suspect its a timing issue.

Re: Boat Takes 1 Hour to Start!

You could be flooding the motor and fouling the plugs from holding the primer (choke) in for to long a time. This will cause the motor not to start untill the plugs have dried off and will fire again. Depending on the time it takes to get from your driveway to the ramp, the motor might not have to be primed alot to get it running if the motor is still warm from running it in the driveway. As for the starter not staying engaged, the top bushing on the starter is probly worn and needs to be replaced. That bushing wares from the tork of the starter againest the flywheel and will not stay engaged at times. A good rebuild shop for starters should be able to do the job on the starter. JMO
