To test the coil you could try hotwiring the coil, just put 12 volts to the positive on the coil. Thats what i did to run my engine on the ground. then just turn in over like normal, if it starts then you know its a connection issue to your coil. To kill it simply pull the 12volts off the coil.

If it runs fine with the direct 12 volts then its something else in the wiring that is your problem.

How long have you owned this boat? Has it ever run for you?


I haven't owned it long, actually i just bought it. When bought the person i purchased it from handed me all the papers from a marine stating the boat was in good working order. It had been winterized, and that ribbon wire that I was asking about, is a replacement trim control wiring harness. I couldn't start the boat at the time, being that it was literally 10below out and the battery that was in it was obviously dead. It seems as tho the rotor/cap wires and plugs are new this season. All the oils have been changed, lower end unit, engine oil, gas and oil filter. That isn't necessary a Great thing b/c now i dont know what the condition of the fluids were that were once in there. DNA's clean..haha...

Don't the coil got to be grounded?

The coil is a direct ground to the engine block.

Umm.....any second thoughts on that? Right now i have everything apart, and id rather not put it back together to just take it all apart again if i can verify the coil's bad. Im thinking of a way to test it w/o having to re-connect everything..


I really do appreciate everyone's help.

Have you been giving it any throttle when you try to start it? You will probably have to pump the throttle to get it started after being winterized and setting. It will not start like a fuel injected car where you just hit the key and it runs.

Listen i can see you know mechanics so you want to bear with me a minute.

Lets get back to the basics, you cleaned all the connections ones on the starter, the neg ground on the block, all the connections shiny clean?

Ok take off the coil from the block and sandpaper a clean ground for the coil.

Put a little gas in the carb maybe a capfull or 2 and put the thottle 1/4 way down in neutral and crank it and see if it starts.

I apologize gentlemen, i haven't been very descriptive about the steps i took prior to getting to this problem.

I have had the boat sitting in my heated garage. I let everything slowly thaw out over a few days increasing the garage temp by 10 degrees every other day...(45-55-65). Once this was accomplished, i put fuel stabilizer in the gas, it had about 1/4 tank of fuel in it. I left the stabilizer in there for a day to see if i could get the alcohol to dry out w/e water may have been in the gas before adding more gas. I left the cap open as well.

I added 5 gallons of 93 octane into the tank and rocked the trailer back and forth to have it mix the following day. I let that sit. Shortly there after is when i checked all the oil fluids (lower end, oil), then i checked the compression, removed all the plugs when doing so. I also disconnected the battery, and the main wire to the cap and the fuel pump harness. I got 150 across the board by the 3rd crank for compression, and then i replaced the plugs just as a maintenance being that I had already taken the old one's out( the plugs all looked good, carbon on the inner ring, seemed good on contact point, showed signs of proper burn), i put brand new NGK's in there that were there cross over part for the ACs that had been in there. I gaped the new plugs to .45 as recommended by the manufacture.

After that i reconnected all the wire plugs, gas pump wire harness, and anything that i may have disconnected, and put in a new deep cycle optima battery. I then pulled off the cover from the carburetor, i took off the flame arrest due to it being exceptionally dirty. I then took off the gas filter and drained it making sure there was not any water in there, and i ran the pump to "flush" out the line. Replaced the fuel filter there after. I then proceeded to turn over the boat, i did pump the throttle prior to turning the ignition. No go. I then added carb/chock cleaner and i had my friend hold open the choke, it fired up, would not stay running, i then checked the wires, as the post above explained, all the wires check out good, all the connections are good, except for the ones i can't see behind the engine block by the coil itself, i see 1 connection that's capped off...im not sure whats back there, i did remove the exhaust bend to get a better view...........and this is were I am at this point.

Good, good and good, did everything right what i would have done except pump out all the gas and put fresh.

Carb, needs a rebuild. That's it.

Filters all cleaned the one in the fitting bye the carb, one in the fuel pump if it has one, and the pickup screen is good and the anti-syphin valve is good and the fuel water sep. is good ok?

Carb is all thats left. Fuel pump is good with 4-6 psi?

Well, thats next on the list, but i may end up, up dating to the 4 barrel carb and the intake if thats the case. However, like i described earlier, it would stay running while i was turning the engine over, and then when i let off the key, it would not run.

But, i guess ill rebuild the carb....man i just love starting projects....i said i wouldn't get to the boat until the drag car was put back together...haha

My guess, is you don't have any gas in the carb. With an empty filter, it will take a while for the fuel pump to fill the filter. If it does. Those pumps shouldn't be run dry for more than 10 to 15 seconds. On engines that have been setting, I fill a NEW filter with new clean gas before installing. (never just dump it and try to reuse, anything in the filter will get on the wrong side of the media)

As a suggestion, put a new filter on the engine, fill it first, then pour about 2 shot glasses of fuel into the carb. Put the flame arrestor in place and start the engine. Bet it runs.

Just wanted to step in and update, i hate threads that just remain in questions if someone else may have been using it to assets them in the future...

I haven't had time to get to the boat, however, don i DID get a new filter for the fuel, and i'll try to wrap everything up tonight and come to a conclusion, hopefully.

Another thing that crossed my mind over the last few days......would an oil pressure switch have ANY thing to do with it not staying running once off ignition?

Nope, not with a Volvo.

Re: 1997 Volvo Penta 4.3GL not starting! **RUNNING!!!THANKS**

She finally RAN!!! After cleaning the majority of the terminals, and making sure all the connections were good, i then replaced the fuel filter, pre-loaded it with fuel, didn't even dump any fuel down the carb, and she fired right up. A little rough at idle..(ive seen most boats run like that). Im sure now that i've got a positive vibe from the boat, ill take the carb out..(most likely up grade it to the 4 barrel), and start cleaning up all the lose ends that i have yet to put together from tearing threw everything.

The only thing is, it has a slight leak coming from i believe the temperature sensor unit on the top front part of the manifold, so its squirting some water out. Other then that, needs a little TLC, that im now looking forward to doing knowing it runs.

Thank you don S, chiefalen and legoman67 for your assistance, time, help, knowledge and patience with my post. Hopefully ill soon be able to contribute to the forum once my know abouts on boats sharpens up a little bit.
