How badly did the marine screw up my engine??

[Gwojcik7]

So I took my 07 SANTE 220 out of storage for the summer, hooked it up to the fake lake and it fired right up first try. I had to have an oil and impeller change done at the local marina so I dropped it off there. They called me and said the starter was bad which I found odd since it just started without an issue. So I figured no biggie I took it home and swapped out the starter. When I tried to start it again the engine would crank then seem like it got jammed and lock up. It would not start and definitely does not sound good when it locks up. Is it possible they put the timing belt back on wrong? What could they have possibly screwed up and what should I be worried about in the future? I am dropping it off today for them o look at tomorrow again.

If it were mine I’d probably pull the plugs and try to turn it over by hand. I guess it’s possible they put the serpentine belt on wrong so maybe the water pump is not working correctly and it overheated but not sure you can do that with the correct size belt.

I agree. Pull the spark plugs and turn it over by hand. I have a bad feeling you're going to find water in the cylinders.

Check the starter for rotation direction. I remember when I was younger we changed the starter on our older Mastercraft and it wouldn’t start, only to realize the starter was wrong. Same model, just different rotation.

Not sure if this is a possibility in newer engines, but may be worth a look.

Water in the cylinders (causing hydrolock) could be caused by lots of things. My immediate concern is that the engine may not have been winterized properly, and if cracks happened in the right place(s), cooling water could be forced into the cylinders by the pressure of your fake-a-lake hose. That water won't compress, and will cause the engine to lock up. Removing the spark plugs will allow the water to escape, and the engine should spin again.

If the starter really did go bad, it is possible that the new starter is the wrong rotation, like noted above.

Who worked on the boat and said the starter was bad?

Sounds like it is hydro locked. I expect that your impeller is bad and it was just starting to get hot when you started it and turned it off. Upon this sequence the motor dieseled and suck water back into the cylinders.

I agree on the sounds of hydrolock. But that’s a pretty crappy diagnosis by your marina to call it a bad starter and move on. Did they winterize it too?

A bad distributor cap would not behave this way: "When I tried to start it again the engine would crank then seem like it got jammed and lock up. It would not start and definitely does not sound good when it locks up"

I'm glad you got it going again, but this still doesn't make sense.

[NautiqueJeff]

Charles is right. No way a corroded cap would cause the engine to lock up. There's more to this story.

I agree something doesn’t feel right about this. I don’t think their telling me the whole story. I may have the certified nautique dealer send a technician out to do an overview on the engine and try to foot the bill to the marina.

A corroded cap CAN cause this issue. If it’s corroded enough, the spark can jump to a different cylinder causing the crank to be forced in the opposite direction therefore seeming like a hydro lock.

I'm sorry, but no. It doesn't work that way. In any given engine, only ONE cylinder at a time is on the compression stroke. A spark "jumping to a different cylinder" would not find that cylinder on the compression stroke. Valves wouldn't be in the right position, no fuel/air mix in the cylinder, etc.

Sounds like it was hydro locked.. I had a 07 220 and blew a belt while riding.. changed the belt on the water and it was locked up. Brought it home and changed the starter and same thing.. Pulled the plug and spun it over and she was full of water. Changed the oil and she ran for another 5 years no issues.

[charlesml3]

There is no timing belt on these engines. They do not run overhead cams.

[Paxdad]

Yes you have to remove the serpentine belt to change the impeller. Perhaps the term they are using is incorrect.
