Gamefisher 9.9.....HELP!?!

[physiksgeek]

I was told that I may get more responses if I put this here. I have lurked on this sight for some time and have enjoyed the information I have found and used. I have posted a few times on here with great success and I feel confident someone here has seen this before. Any help will be appreciated.

Without being to winded....I bought this motor new in '96 (225) I put maybe 50 hours on it before I sold my boat. I kept the motor and stored it in my garage for 10 years without ever running it. I drained the gas and put WD40 in the cylinders but only once over those 10 years.

I bought a new boat and trailer to go with the motor. It started quickly after I put the gas to it but it would not pump water. It did run till it shut down hot(I do not know if it was because of the gas or what but it was definitely hot when I tapped the cylinder cover with wet fingers). I dropped the lower unit and sure enough the impeller was shot. I ordered the new impeller and while it was shipping I checked compression to make sure that was o.k. and was not hurt by getting hot - 150'ish each cyl.

Impeller comes in today. I put it in and go to start it and after the third pull it almost dislocated my fingers. After checking a few things I figure it is was a compression thing. I pull the plugs and a white milky mixture is on the bottom spark plug. I pull the cord and more milky stuff comes out of the bottom cyl. I am lost....It never did this at anytime over the last week especially not during the compression test. I drop the lower unit again to check for anything obvious.....nothing. I pull the cord some more and it is doing the same thing with no end in sight.

I am thinking this
1. Water in the fuel tank, now in the carb, now in the cyl? It is being emulsified by the compression?
2. As I spin the motor the new pump is putting water in the jacket.....cracked cylinder? The compression does not indicate this though?
3. Did something happen when checking the compression, i.e. scarred the piston?

What do you think? I appreciate any help or insight........

Is the gear select lever in neutral? If it's in forward or reverse the engine will lock while the pull start cord is pulled, safety feature.

#1 possible, but since it ran fine right before this I kind of doubt it. Put some fuel into a glass jar to see if there is water in the fuel, pump it out of the tank with the hose as the water will be on the bottom. Clean fuel tank and refill with fresh fuel/oil if in doubt.
#2 The comp#'s don't show there's a problem, 150PSI is very good
#3 Scarred piston/cylinder would cause low compression, not milky oil/fuel mixture. Cracked head or cylinder could cause milky stuff.

Honestly, I'd pull the plugs, squirt some 2 stroke oil into the offending cylinder, turn the engine over a few turns to displace the water/oil, replace plugs and start the outboard. Run it for a bit, let it cool down, then pull the plugs to see what's in there.

How long did it run without water flow, before it got hot. Was it smoking hot to where paint started discoloring or just hot to the touch? I kind of doubt you caused damage by 1 overheat,,, but you never know.

Re: Gamefisher 9.9.....HELP!?!

I didn't look good at the pics, that is some nasty looking stuff in the bottom cylinder. And, the bottom cylinder is showing 170PSI (odd since it's the one showing problems)

I would do the same as I suggested and see if you get the same stuff coming out of the bottom cylinder. Could be a head gasket leaking because of the overheat, but the comp #'s don't make sense. Maybe that milky stuff is sealing the cylinder better than plain fuel/oil?

BTW, if it was coming from the fuel tank both cylinders would have the same milky stuff as they feed off a common carb.

By looking at the motor you could not tell it has even been hot, i.e. not discoloration, not peeling paint, etc. I would have thought that if it was coming from the fuel tank (which by the way is the tank that came with the boat and trailer) it would have been both cylinders. The compression puzzles me also.

After thinking about it overnight I am going to pull the thermostat and put a water hose on the water pick up tube out of the impeller housing and see if any water ends up in the cyl. If I find nothing there I am going to empty the fuel tank, pull the gas lines and drain, turn it over till it clears up and start fresh. I will keep everyone posted.

I am starting to lean towards water in the fuel because no longer than it ran (first time 30 seconds, pulled the thermostat and the second time maybe a minute and a half) before it shut down I would not think it fried the motor. Besides......where else would the oil come from?!? I am truly puzzled!

Re: Gamefisher 9.9.....HELP!?!

The increase in compression could be coming from the water/oil mixture sealing the rings up . Your idea with the hose might work, keep us posted. MOPARMAN

Re: Gamefisher 9.9.....HELP!?!

O.K., so I walked straight up to the motor this afternoon and found a wetspot under the motor. I disconnected the gas tank and pulled the start cord...SUPRISE....it shot gas out of the bottom cyl which hit the side of the cowling and then into my face. I don't mean a little gas, I am gonna guess a half a cup full on the first pull. and a little less each successive pull. I went in and took a shower and came back and got gas for several pulls after that.

I drained a quart of gas using the tanks bulb......looked good.

I then put a water hose to the water pick up tube w/the thermostat in to give it a back pressure. The thermostat was slightly open so I got flow with no obvious signs of water in the bottom or top cyl. Pulling the start cord produced only gas residual. I did this several times and I feel confident that there was no water in the cyl. After all the pulling it looked like the cyl dried up in fact.

I went on to pull the carb and lines to drain those......found the float "stiff" and a with a few deposits. The float does not "free fall" like I think it should.

So here follows my logic......the float was stuck or became stuck in a position to allow constant flow. When I look back I put the motor on the boat after pulling the boat home. The tank sloshed during transit so there was less ability to suck straight water. As it sat over the next few days the water settled. Initially it drained the water from the gas tank into the bottom cyl.......which I saw the result of yesterday. Today it was straight (or a very high percentage of) gas. I will make repairs to the carb and test.

Does this sound plausible? I also need a repair kit FK10295...is there one available through this site?

Thanks for all of the input and any future input.
