My husband needs the point gap , timming & dwell settings for 1978 351 ford windsor that is in our boat. Is there a link we could get this info? Or does anyone have this infoThanks Sandy Chuck's wife

I would look up a Websearch for the brand of motor and the year and engine size. Marine engines have different camshafts and timing is different than on an auto engine. You would look up Mercruiser if it is an inboard/outboard outdrive and has Mercruiser emblems. Same for Volvo or OMC embled outdrives. Ford makes the basic block but the specs go by outdrive makers.

This is because the gearing in the outdrives make a difference in what the engine needs to do.

Can water be forced up past pistons in a 5.7 350 mercruiser.

you would not get sufficient water past the rings to cause what you describe
there has be a fault in the assembly as the water is getting in past the water manifold into the intake to suck water in on top of the pistons do you have an operational back flow valve in the exhaust to stop water being sucked back into the engine past the open exhaust valves on shut down
are you running an oil cooler in the system that could be a reason for water in the sump oil if it is leaking

Mercruiser boat 1989 3.7l/LX 4 cyl. 3&4 cyl is not firing. New plug . Contact Pt.wires, distributor cap.start right away,

Try to ensure you have the correct PT Wires connected in the right order of firing, This should be on the side of the engine near the top either side it can on, I am sure that is your problem. Best Wishes. Malcolm Campbell.

I have a 2006 20' boat with a 4.3L Vortex engine. The started needed to replaced and after further inspection the starter looked rusty. Removed spark plugs on left side of engine and rusty water came out...

he bore on that side will be rusty so the engine has limited life
the water could be from a cracked head or head gasket problem
if the engine is at water line in the boat
, if there is no exhaust flaps at the rear of the boat , then on shutting down the engine water could have been sucked back up the exhaust on that side into the engine
( cooling manifold creates a vacuum which will suck in the water

1990 454 mercruiser misfire under load when warmed up

Running on a stand is not the same as running under power...In the water, you are essentially running on a dynomometer (dyno is a big water brake) If you can prove that the module isn't putting in enough advance, it would be doing the same thing that I mentioned with the damper, only for a different reason.'re likely on the right track. (rather have a points setup out on the water...anything goes wrong, you fix it without a tow!!!!)
Good luck

I have a 1987 mercruiser alpha one out drive the boat sat for 5or 6 years engine turns over but no spark also had water in the cylinders drained the oil filled the cylinders with mystery oil let it sit for...

Alpha One is the out drive, what engine do you have? Remove the distributor cap and verify if your ignition is electronic or contact points. Either way, I recommend going with a Pertronix electronic ignition. This module is a simple drop in installation and will eliminate a major portion of your troubleshooting. Pertronix also has a high output coil to accompany their ignition, I recommend you install both as a set.
FYI, water in the cylinders is not good. Especially if it sat for 5-6 years rusting the rings and cylinder walls. Was this boat running when it was parked and do you know the history?

Chriscraft w/ Mercruiser I/O wont raise completely

there is an up and down button and then a seperate trailer button to raise it further. it uses the same system to continue to raise it so you may have an issue with the trailer button.
