Cannot See the Telltail Water Stream from the Motor
No, I really don't want to DIY repair the motor. As mentioned in
another of my post in this thread, I am fixing the rotten core of the deck and the deck core is exposed, and is not in the position to bring the boat to a mechanic and risk getting rain water inside the deck again. I just want to do enough on the motor to be able to finish winterizing it. Next spring or later when I am done with fixing the deck, I will bring the motor to a marine mechanic (my boatowner neighbor has recommended a really good mechanica in my area) and have the motor checked out and also to look into a few things. Thanks for the suggestion of a couple good reference books for maintaining motors. Also thanks for suggesting to buy those books from eBay at a low price.

(If I were in your position , I'd take it to a reputable mechanic). BUT, i would get a repair manual for that model or series of engines. like a "Peterson", "Chiltons" or "Motors" or likewise book that you could study really well, A book that will tell you in great detail on how to even overhaul your engine if necessary. A vast amount of knowledge can be found in these books. just for if anything else, a reference point. You can find these books at about any boat dealership, or what i did was bought an almost brand new manual for my mercruiser off Ebay, for less than half price of what the stores wanted. For my book, the dealership retail price was about $49.00. I bought mine with a high bid of $18.00 plus $3.75 s&h. wrote: wrote: wrote: I left the boat in the driveway for one year without starting the motor. Today, I put the lower unit into a bucket of water, and start the motor to winterize it. Jay, just out of curiosity, if you haven't used the boat in a year, then why are you deciding to winterize it at this time? According to what yoyu say, it must have sat all through the colder winter months of last year,a nd the first part of this year. why now? The reason of winterizing the motor even without using it for a year is: Last fall when I winterized the motor, I didn't run the fuel system dry. I ran the motor for 5 minutes to let treated fuel get inside the fuel system and then I shut down the motor. This means there is still fuel inside the fuel system of the motor. Although the fuel was treated with stablizer, it will only be good for one year. If I didn't winterize the motor now, by next spring the treated fuel would have sat in the fuel system for 17 months -- that would be 5 months longer than what the treated fuel is supposed to last. This is the reason why I need to winterize the motor now. Jay Chan |

Cannot See the Telltail Water Stream from the Motor
The brass key pin is there, and I vaguely recall that I had turned the
driveshalf to verify that the brass key pin can turn the impeller. But I don't trust my memory. I will try this one more time today when I get back home. Thanks for the tip.

Today, I put the lower unit into a bucket of water, and start the motor to winterize it. After trying to start it for a couple times, I finally manage to start it. Unfortunately, I cannot see the telltail water stream coming out from the motor cooling system. All I see is some smoke coming from the hole where the water stream is supposed to come out from. Despite the fact that the motor temperature was not overheating (only run it for 30 seconds or so), I decided to turn off the motor just to be in the safe side. My question is: Should I expect to see the telltail water stream coming out from the motor as soon as I start the motor? Does the motor need to reach a certain temperature before the water stream coming out? The boatowner manual said this: "2. If engine is cold, run engine for 1 or 2 minutes ... 3. After engine has warmed up, check water temperature gauge to ensure that engine temperature is not abnormally high... Check that water is running from the tell-tail on the back of the engine..." This seems to suggest that the telltail water stream may not come out if the engine is not warm enough. Considering the fact that the overheating warning horn doesn't sound, the cooling system may not really have a problem. However, the Mercury Operation & Maintenance Manual for my 1995 Mercury 115hp outboard said this differently: "10 Turn ignition key to START ...re-prime until engine is running smoothly. 11 Check for a steady stream of water flowing out of the water pump indicator hole. IMPORTANT: If no water is coming out of the water pump indicator hole, stop engine..." This surely seems like I should expect to see telltail water stream coming out as soon as I start the engine. Now, I am really confused with this conflicting info. Obviously, I don't want to risk overheating the motor. Can someone help me with this? Thanks in advance for any info. Jay Chan I thought the impeller was damaged and could not push water through the telltail. Last weekend, I opened up the impeller and found that it is in very good shape. Now, I really don't know why I cannot see the telltail water stream when I start the motor. At this point, this problem is beyond my skill level. I will bring the motor to the dealer next spring and let them to fix it. Meanwhile, I can only finish half the winterizing process (fuel system is only partially winterized). I will just have to try my luck and hope that some of the treated fuel managed to get into the fuel system of the motor when I ran the motor for 30 seconds two weeks ago (I am betting on this because I know that I had used up all the old fuel from the fuel tank before I ran the motor). Thanks for all the people who have tried to help me. I appreciate that. I will let people know how this goes next spring when I will bring the motor to the dealer. Jay Chan |

I think you missed my point. with the impeller still on the shaft, pull hard
on one of the vanes. Any separation between the impeller and the collar it is glued to is very bad. Jim wrote in message oups.com...

I re-read your original suggestion, and I realize that you were asking
me to check that the key-pin and the impeller are bonded together well. When I lifted up the water pump housing to check the impeller, the impeller stuck with the housing, and the key-pin fell off. I don't know if this meaned the key-pin didn't bond well to the impeller or not. Anyway, I will try what you have suggested when I get back home. Thanks.
