Hi gang! Welcome back for another year! Here's my latest misadventure with my 18' 1988 Bayliner Capri with an OMC I/O.

When I put the boat in winter storage, everything worked fine and nothing leaked. I got it out a couple of weeks ago, put the muffs on, it fired right up and ran just fine.

Was working on the trailer a couple of days ago and was putting it up on jack stands. I misjudged the center of gravity just a little and the trailer tilted back as I was jacking it up and the lower unit/prop hit the ground; not really hard...I didn't pay a lot of attention to it actually, but it did hit the ground (no visible damage). My wife pushed the tongue to the ground and I jacked it back up and moved the stand to another brace on the trailer further back.

This afternoon, went down to the marina and dumped it in the river for a test ride. On the way, stopped and put a full tank of hi-test gas in it. Started right up again and off we went. A couple of miles up the river, I wanted to stop and hang out a bit, so I slowed down, As soon as I did, the engine stalled. It took me a solid 15 minutes to get it started again. It would start (with difficulty), but would die as soon as I put it in gear. Finally, I jammed it in gear and got it going and we headed straight back to the marina. All the way back, it ran really rough and the engine sound was not consistent. Seemed like it was losing power the whole way. At the time I was thinking plugs(?) fuel filter(?). As soon as I slowed down to turn into the marina, it died again. Again, 15 minutes to get it started and we hobbled back to the ramp.

I got it on the trailer and pulled it up into the lot. Pulled off the engine cover for a peek, and the bottom of the engine compartment was full of water! Like, probably about 10-15 gallons. It was, basically, even with the battery compartment with the boat trailered.

So, (1) have I just "developed" a leak somewhere or did I damage a seal or something when the unit hit the ground? Where would I look and/or how would I figure this out? And (2) would the water in there be causing the engine issues I was experiencing? I guess I'm trying to find out if I have one issue or two. LOL.

I want to see what you WONDERFUL people think (that's a plea for help, by the way) and then I guess I'll head back to marina Thursday and see if I can do even MORE damage. Am I dealing with one issue here...or two?

Thanks everyone. :)

I doubt the skeg impact caused a leak into the bilge. You need to establish how/where the water is getting in. If it's leaking from a hose connection between the steering oil cooler and the thermostat, it could be spraying on the distributor/plug wires, causing misfire. Put it in the water, lift the engine cover, start it and look for water. If you accumulated 10-15 gallons, it will be very obvious.

Thanks wire2. I was really afraid that I had busted some kind of a major seal where all the mechanics go through the transom. I like your idea MUCH better...though I didn't see any water like on top of the engine. I guess we'll see Thursday.

Any other theories out there I should look for? Anyone? :)

Hopefully its not because your transom is weak from rot and you just tweaked it enough to start the leak.

Could be your bellows and its just a coincidence with the timing of it. Did you pull your drive this year like you are supposed to every year?

Pull...my...drive...??? OK. No way to get around this without looking stupid, so I'll jump in. I take it to the marina and tell them to winterize it, then I put it in a barn. Although, slowly but surely, this thing is turning me into a driveway mechanic. But, in the great scheme of things, I have NO IDEA what you're talking about. :-( I do know they replaced the impeller last fall. I spent most of my summer replacing the starter, among a half dozen other things...

Just in case we are keeping notes, or some poor fool is searching forums because he/she is having the same issue, what I described earlier can also happen when your HEAD GASKET FAILS. :facepalm:

So, the answer is to order a gasket kit (from iboats.com, of course) and find "that guy" who hangs around the marina who makes a little extra cash tearing engines apart. Take the head down and get it checked and planed (might as well, while you're in there, he says...) and put it all back together.

The water, by the way, was VERY obvious once I put it back in the water and started the motor. Water was pouring out... :eek:

I'll let you know how it turns out...

Re: What have I done to my boat?? Grrr. Help appreciated...

The u-joint bellows may have loosened up when it hit the ground. If it did it would easily allow tham much water in. It sounds like water sprayed up onto the wires/distributor making the engine run rough. In any case, the drive has to come off to check the bellows, gimbal bearing & u-joints. Get a grease gun pronto & grease the hell out of the gimbal bearing to force any water out of it. But, if it feels rough when u spin it, then it's shot.

Can you be a leeetle more specific?


Was the water "pouring out" BEFORE you started the engine or after?

If it was AFTER, I would say you have either have a busted power steering cooler, broken raw water supply hose or fitting/pipe etc......(OR :eek::eek::eek: a cracked block, popped core plug commonly and mistakenly called a "Freeze" plug.......)


If it was BEFORE the engine was started just sitting in the water, it could be the aforementioned bellows, transom seal etc.......

It's the transom seal. Same exact thing happened to me. When I pulled my boat out of the water once the crank strap broke so I rigged it just to get it out of the water so I could replace it. Once I got it to the parking lot, I decided to unhook the boat/trailer from the truck so I could run to the local store to get a new strap.

Well, same thing happened, boat tilted back since it was sitting too far back the trailer and sat on the skeg. Didn't seem like it damaged anything at all. Nextime I put it on the water same exact thing happened, water was flowing in but never hit any part of the engine. I think it just moved the gasket just enough to let water in. Thank God my bildge pump worked like a charm.

I didn't have it fixed the right way just did a band aid job with water weld sealing the transom to the outdrive. Been two years and it still works. Added another pump just in case.

Tighten the 6 transom-housing bolts, your leak will stop as long as it's not the drive-bellows.

I'm a little confused......how could his problem be the same as yours?

The transom seal just doesn't start leaking profusely on it's own.

If that happened to your boat....you NEED to pull your drive and check/adjust the alignment or you WILL be pulling the engine to replace the coupler in the not-too-distant future..........

And after you do that.......pull your drive and check and adjust(if needed) your alignment too......or you too will be replacing your coupler (after pulling the engine)

I think he just told us he found out it was a head gasket!

I have a question, did you make sure the pet- **** drains were closed on the heads, before you took it out on the lake?

Re: What have I done to my boat?? Grrr. Help appreciated...

Yes - it was the head gasket. Boat sat in the water just fine - started leaking when the engine started. Stopped leaking when shut off.

I have discovered now on two occasions (which should tell me something...) that my engine does NOT run well with a bilge full of water (the first time was a poorly placed screw trying to hold down the battery compartment, but that's a whole 'nuther story).

So - I got pictures for all the fans out there. The first is the general orientation of the engine, the second is the right side of the engine, and the third is as close to the leak as I could get with the engine in one piece. You can kind of use that red cable to keep oriented. :( I DO have a bilge pump (never occurred to me to use it out there, because I had ZERO reason to believe it was full of water). On a switch...not a float.

Anyway, the head and the manifold are at a machine shop getting tested and planed, the new gasket kit should be here Tuesday, and with a tiny bit of luck, we should be good to go by the end of the week (unless the testing comes back bad, in which case...well...now we're not even going to think about that now, are we?? :facepalm:) At first glance, both the mechanic as well as the guy at the machine shop said the engine was surprisingly clean. Reckon that's good news. :rolleyes:

By the way...you guys all ROCK. Thanks for the help, input, and suggestions. If it wasn't for iboats, I would have pushed this thing off a cliff by now.

By the way, it's probably good to keep in mind that ANY raw water leak on an engine or component in a boat that sits in the water can literally sink the boat if given enough time, if the leak is below the waterline.
