E-XP 150 Powerhead Exhaust Gasket

[MASTER Brian]

I hope I'm saying this correctly....I have a 1986 Evinrude XP150 and it apparently has gotten a small exhaust leak where the power head mates up to the mid unit. I rebuilt this motor about 10yrs ago and when we went to set the power head on, we thought the gasket partially tore, so we added some extra liquid gasket sealer and hoped for the best. The way we saw it, it'd be a week or two to get a new gasket and we were already there ready to bolt on, so if it didn't hold we'd just go back and fix once I got the gasket. Needless to say, I ordered the gasket way back then so I have it and it finally started leaking, so it's time to replace it. I'll look back in the manual and also look for some you-tubes, but I'm curious if anyone can tell me how long this should take to perform? I figure while I'm at it, it's not too much more work to replace the water pump, so I'll get one ordered as well. I'm getting good pressure on it still, but it hasn't been replaced since the rebuild....I know that's a long time, but I had installed a gauge and I have the tell-tale, so it's been well monitored. Do I just replace the rubber impeller or buy a whole kit?

As for the gasket, should I just be able to just lift the power head straight up, slide in a new gasket and go down the road? I'm guessing I unbolt the 4-6 bolts that hold it to the mid unit, unhook the linkage and that should be about it....am I correct? Since I don't have easy access to an engine hoist, I'm either backing it into a neighbors garage and using his electric winch, which hangs from the rafters to skin deer with or I'll take some scaffold and hook a chain hoist to that.

Any idea on weight, 200lbs? time frame involved? Shop wanted $400, which seems expensive.....is that worth it?

You Said you rebuilt this before, which would have you removing and reinstalling the PH, No?

6 long bolts, 2 front bolts, 2 front nuts, 2 rear nuts. Front pan bolts, telltale, harness, shift linkage, fuel line....Suggest you get a manual for a step by step. As there are other items to do.

Its heavy, recommend a lift. Worth doing if you can do it. Pay attention to getting both surfaces clean of old gasket and crud, make it very clean.

Yes, I did rebuild this before and yes it had me removing absolutely everything. Problem is it's been 10yrs and I don't recall the difficulty or lack of difficulty of removing just the power head. That said, I did help a friend pull apart the power head on a 90's? Johnson 140 last summer, but there again, we stripped most of the parts off while it sat on the top of the mid shaft because it was just easier. Turns out his cylinder was toast and a rebuild is not in it's future.

I do have two manuals, I bought the first one and then was told the 2nd one was actually a better manual, so I bought it. Can't recall which ones they are but I'll dig them out, but as I believe I said, they don't always paint a clear picture of the difficulty of the task.

I'll see about getting a picker or lift of some sort. From what I recall the auto picker going in at an angle is what caused it to scrape and thus tear the gasket from what I recall. This is why I've thought about going straight up and straight back down.

Thanks for the feedback, sounds like the bolts and linkage is what I thought was in the mix. Hadn't really taken the fuel line, battery cable, etc into account, but I know they are there and need moved....

Been a busy summer, but I'm finally getting to this. Ice got the manual and am going through it, but I'm wondering how much of this stuff I actually need to actually unhook and remove. Planing on using electric winch my neighbor has hanging from his rafters in garage. He uses it to hang deer, so we know it'll support the power head and thus I'm hopping I can go straight up, swap out and go straight back down. Last time I used an engine hoist which went Ary angle thus the tear of gasket.

OK, my motor is a 1986 Evinrude XP150. The stampings on the motor are E150STLCDc, when I research this, I come up with this gasket. I didn't think this motor was a crossflow, is it? Should this be the correct gasket? When I went to get my gaskets, turns out the one I thought I had to replace it wasn't the right one, it's for the airbox. I do have a bunch of other gaskets as when I built this motor 10yrs ago, they sent me the wrong ones, I thought I ordered the base gasket at that time, so not sure. I have most of the PowerHead ready to pull, but realize I don't have a gasket on hand, so I want to order before going further. To clarify it is the gasket mounts the PH to the MidSection and I'm dealing with an exhaust leak at this point. It's just been too long to remember. All that is left is to loosen the 6 long bolts from midsection to PH, release the drive shaft and I think that's about it. I might have to remove a few other misc items, but I'll take care of those as it gets in the air and I see how much room I have to work with.

FWIW....I'm thinking I might just go ahead and replace the waterpump at the same time, I did a complete kit back in 2006 when I rebuilt the PH, haven't done a WaterPump since, but hours haven't been huge on the boat, I have not only a guage but a tell tale and I've never had any issues, but thinking it's past time. Should I buy a complete kit or just the impeller? What is the deciding factor on this?

Don't use a aftermarket gasket only OEM. The original as superseded several time as they had problem with what your experiencing.The new OEM gasket has built in sealer and aluminum reinforcement....

Thanks for the heads up! I'll find an OEM gasket tomorrow or later tonight. It does appear that's the correct gasket to me, are there any others that will need replacing when I do this one? I have no other leaks, just want to insure that when I pull the bolts that mount the PH to the MS, nothing else is in there that needs replaced gasket wise....it's been too many years since I have done this and originally I had purchased the PH gasket kit.

I had actually found one at *boats dot net, they seem to show lots of OEM stuff, but does anyone know if it's true OEM? Any suggestions on place to purchase? I'll search this site later as well. I had just done a quick google earlier to get an idea of what it looked like. **On 2nd look it appears the one in the link is OEM, the one on this site isn't...correct if wrong.

This appears to be OEM, I'll call tomorrow!
