Sedz 15 Posted June 6, 2016 Share Posted June 6, 2016 (edited) FRESH PLUGS...PROBLEM SOLVED hey guys, we have a GM Vortex 5.7L (340 hp) motor in our wakeboard boat that won't accelerate under load. With people in it and some ballast it can't get over 13mph. It was left in the rain by the marina before being covered up wet and stored for the winter. We picked it up and its a horrific mess, had to replace both batteries and a new starter just to get it running (the 'marina' couldn't get it running in 2 weeks of 'trying'). I suspect that they either entirely forgot to winterize it or improperly winterized it. On the weekend we replaced the distributor cap and it can get up on plane with no weight or passengers but still runs like shit. In neutral the engine seems to run half decent. Anyone have a suggestion on what could be causing this? Edited June 21, 2016 by Sedz Quote Link to post Share on other sites
2strokemerc 2,755 Posted June 6, 2016 Share Posted June 6, 2016 Is the distributor in the right spot, sounds like timing. Quote Link to post Share on other sites
Puzzleboy 603 Posted June 6, 2016 Share Posted June 6, 2016 How old is the boat? Check timing as Merc said...... plugs and wires might be wise also. Quote Link to post Share on other sites

Still has relatively low hours on it. Hoping to get a few things to check next so I don't waste another weekend trying to get it running properly. I'm sure a real marina with diagnostic computer could figure out the issue in 5 minutes but my old man refuses to go that route cause all his friends seem to think they're experts and can fix it themselves.

Anyone have a suggestion on what could be causing this? Start by draining and drying the hull. Nothing like leaving a boat outside uncovered and protected in the rain and snow......once done baseline the engine. The usual fuel, oil, spark, prop, lower end......find a new Marina after you send them the bill..... Quote Link to post Share on other sites

Nothing beats a Brechin tune up. Fiddle around with it for a bit, then start it and rev the piss out of it. If you need a good guy to look at it Give Brian at On Your Way Marine a call.

Sksman 331 Posted June 7, 2016 Share Posted June 7, 2016 Trade it in on a new one. They wont water test it. Then next weekend your boat will run like new. Quote Link to post Share on other sites

There is an easy resolution to this which is just taking it to our tige dealer, port sandalled marina would have this fixed in 5 mins I'm sure.

Dave 7,108 Posted June 9, 2016 Share Posted June 9, 2016 Sounds like a fuel pump issue to me. Quote Link to post Share on other sites
lastzrt 40 Posted June 9, 2016 Share Posted June 9, 2016 Swapped out the cap but not the rotor? There is also a screen on top of the distributor shaft housing that would get clogged/rusted up after moisture intrusion on the Vortec's. Check it, you can punch it out or replace the housing.

However, now after sitting exposed to rain and snow.......not to mention the fuel system was found empty the boat now runs like shit...... it ran perfect. They said there was a cooling system leak and both batteries were toast. $1700 later we were ready to pick up a boat that didn't actually drive in the water. It went exposed to snow, it just clearly sat out uncovered in the rain and rather than letting it dry they just covered it and said fuck it. Its literally black with mould inside. They did the same last year but also tracked muddy boots in and out of it and didn't clean anything, they said they would send someone over to clean it but were still waiting on that 3 hours ago, smokin george said: Maybe they used it for ice fishing haha yeah until about mid jan they could have open water fished. 2 hours ago, DAVE said: Sounds like a fuel pump issue to me. 1 hour ago, lastzrt said: Swapped out the cap but not the rotor?

Poncho 898 Posted June 9, 2016 Share Posted June 9, 2016 Then clearly they dropped the ball. They owe you the better part of 1700 dollars and an operational boat. Go after them or bill them for work done. They know exactly what happened with your boat, it was in their hands. Quote Link to post Share on other sites
bladefever 1,537 Posted June 9, 2016 Share Posted June 9, 2016 Been a few years since I have looked at a Merc engine. Does the distributor have mechanical advance for timing? Maybe seized from the deluxe storage package. Quote Link to post Share on other sites

Talked to a lot of friends and everyone says that they guy running the marina has just given up and doesn't care anymore. They didn't pay to fix the damage their roof collapsing on the tower of the boat cause. They tried to blame a prop that was folded in half on us as well. When that didn't fly they put a shitty used prop on it in place. Quote Link to post Share on other sites

There is no amount of speculation that can help your problem until you know what you have now. Quote Link to post Share on other sites

Any damage to your boat should have been handled by your insurance company, a marina is not responsible if a roof collapses while in their care Quote Link to post Share on other sites
bladefever 1,537 Posted June 10, 2016 Share Posted June 10, 2016 That prop was probably a variable pitch prop. The more power you applied the more the blades folded. Quote Link to post Share on other sites
