I think in my case it was ignorance, I was diagnosing some intermittent electrical issues and it was started and run for brief periods of time out of the water. I made a whole host of problems for myself with that bonehead move, but it will be a lesson I will not soon forget!

It sounds as if you have some rubber impeller debris inside the water passageways.

Yes, you can pull the RH water jacket assemby off & on these post 92s you do not have to pull the block beforehand.

However if you look at the diagram & unscrew #6 plug screw while it is running, if any depris is in there that is to large to come out the tell tale hole, it may come out this motor flush hole.

If that does not do it, then you may have to pull the head & possibly the water jacket to be able to be sure there is nothing inside.

Replace the thermostat.

Should I also pull off the panel on the right side of the motor where the tell-tale comes out? It looks like I'd have to remove some linkages to get to that point, but is it possible there could be some crap in there too?

I know on the earlier models (like my '85 9.9) you have to pull the power head to get to that panel because a motor mount blocks one bolt. I'm fighting this same issue with my '85 so post you progress and findings. Hope this halps a little.

Ah, good point on the flush screw, I wondered what would happen if I opened that up. That will be the first thing I try tonight I think. If not, I guess I will end up pulling the head, and if it's not too labor intensive I may do that anyway just for peace of mind.

So I pulled the panel off where the tell-tale comes out, and there were numerous rubber debris hung up in the little passageways, and the gaskets were in really bad shape. I also pulled a large piece of rubber out of the bottom hole inside that panel, it was almost completely obstructed there. I am still having overheating and water flow issues though, so I guess my only option at this point is to pull the head. I have a new gasket on the way for that. I'm beginning to wonder if I wouldn't be better off just buying a new motor, I'm starting to get pretty frustrated with it all. I have a new head gasket on the way, as well as a whole thermostat assembly to replace the one that was missing. I can only think however that the previous owner would remove the thermostat completely if they were having overheating issues. If pulling the head doesn't fix it, then there must be debris between the powerhead and the copper pickup tube, and that will SUCK to have to take that apart. I'm having my doubts about this motor, I've already put a new starter, new wiring harness, and now all of these parts on it. Beginning to think I'd have been better off keeping that cash and putting it towards a new motor!

Jim. You have learned a lot about your motor. I've been where you are right now. As the saying goes," The darkest hour is just before dawn". Your probably really close to getting things working. Go ahead and pull the head while your waiting and get picking, scraping and/or whatever you need to do. Rick.

Yeah, I feel like I've rebuilt this thing from the ground up at this point! Today some parts came in, so I decided to install the new thermostat I just bought (since mine was completely missing) and I pulled the head to look for debris while I was at it. I found no debris at all in the head, just typical crud from saltwater use I imagine. I found no scoring or damage inside the cylinder walls which is always a relief. When I went to pull the head I found that the casing on my powerpack looks melted and is cracked. I submerged my motor the other day and it started having issues starting and staying running, felt like it was bogging and just struggling to stay lit. Tomorrow I am going to go to the local boat shop and pray they have a new powerpack and I may buy a coil just to eliminate one more issue and gain a little peace of mind. While I was pulling the head I also dropped the lower unit. I ordered a whole water pump KIT (rather than just an impeller) just to eliminate one more problem area. I'm going to install all of that stuff after I make myself some dinner. While the lower was dropped I hooked up a garden hose to the bare copper water tube. I blasted a bunch of high pressure water through the whole system while I had the head off, and water seemed to flow freely and easily through the water jacket and head. I am hoping that I will be back on the water and running reliably if all goes well tonight/tomorrow. I have been missing having an engine for sure... my trolling motor is slow going in any sort of current and I miss having a longer range when it comes to my fishing. Thanks for all of the advice everyone has given me, hopefully my luck turns around and I'll be running smoothly soon.

If it still runs hot, you need to pull the powerhead and replace the water tube grommet.

I am hoping it doesn't come to that, it sounds like a lot of work. At this point though, what the hell, can't be but so hard I guess.

I put the water pump kit on a few minutes ago. I decided to run it in a small tank of water, using a drill to turn the driveshaft. It didn't pump water, because I'd left the metal plate out. Doh! Glad I tested it first. Once I put the plate in, it pushed water. I'm not sure how much it's supposed to pump out, but it was pushing water pretty good even at low speeds on the drill so I imagine it will once it's running also. Tomorrow I'll bolt the lower back up and put on the new power pack and see how she runs out.

Well, the parts finally came in and I had time to install them. I put on a whole new water pump kit, exhaust housing gaskets (I found rubber jammed inside the exhaust housing) as well as a new power pack because mine looked melted and had water inside it. I was having a hard time starting the boat. It would fire and then immediately die. I decided to disconnect the black wire with yellow stripe to see what would happen and it fired right up and ran. As soon as I connect the wire again, it starts to sputter and die. It is idling fast now, but I'm wondering why the hell the boat sputters and stalls once I connect the kill switch wire. The wiring is in great shape as far as I can see so the only thing I can think is that maybe I'm getting an intermittent connection at my ignition switch? I replaced the switch a couple of months ago so it seems odd. As far as my water problems, it is running and peeing great while hooked up to the hose, but we will see how it does once I hit the river. In the past I've had problems once the pressure from the hose wasn't assisting things. Also, is it normal for the prop to turn while the boat is at a fast idle and in neutral, or did I connect my shift linkage wrong? It doesn't spin fast but it does spin at a good clip when it's at a fast idle. It shifts into forward and reverse just fine.
