sparepats... are you thing , like you posted yesterday, that it is the stern pump. I have a lot on motorcycle experience, but no much at all on boat wet systems. Thanks for all advise

the water pump in those drives is a weak point, they only have to run dry for about 20 sec before they are damaged, they will also get brittle and break the blades off if they sit for long periods of time. Go ahead and drop the lower unit. Do a search on utube, there are probaly several videos of people doing a water pump on a mercruiser(I'm going to make a video of it one day), i'll give you two hints, drain the fluid out first, and put the gear shift in fwd gear before you drop the lower. Between Ferm, Skools and myself, we've probably explained it 30 times on here, do a search for water pump replacement

Thanks....been looking at all the video feeds I can find on the internet. The manual's pictures are very hard too make out. Wish thet were in color instead of B/W.

Spareparts, what are the most important things I need to pay special attention to when dropping the lower unit and making the repairs to correct my water intake flow problem? Any special tricks/tips I should be aware of?
Thank you for your help.
Do you & Destroyer feel this is most likey my problem?
** Note - My boat pics are on my profile page

I see now why my water pump is bad, as I was taking off the lower unit I noticed some areas that had been epoxied and painted over. Guess what, the whole trim tab casting on the upper half of the motor broke off. I traded the boat with a horse trader. Can this type of "pot metal" be welded or am I just up the creek wihout a paddle. I'm going to post a pic of it in my album. If any one has any ideas, suggestions, solutions or other ideas than sinking her, let me know. I've contacted the fellow I got the boat from asking to reverse our trade...doubt I get far with that one. Live & learn.

they weld on those lower units all teh time, just find someone whos familure with the repairs, try a prop shop

Thanks - was hoping it could be welded, but it burns my rear knowing this guy sold it to me like this.....very good lesson learned..buy a boat on a warm day and insist the owner take you out for a test ride. Ha! I'll call on some old buddies that have welding experience and see who they can recommend. I guess it's time for a cold one and wrap it up in plastic.
Thanks again SP....this is a really great site!!!!!!!

Tough break....similar thing happened to a friend of mine....guy had all sorts of JB weld inside the drive to keep it together long enough to get it out the door basically. Live and learn they say...

On another note....when you had the boat in the water was it floating like your bottom paint line shows?.....seems like the back end is sitting WAY low in the back.

this could be just the beginning of your problems now that you have the lower unit off take the upper off and see what it looks like. oh you can still get a garden hose and connect the hose [to the hose that is]off the inside of the transom inner housing plate. this little tube years ago used to rot out a little [copper] causing trouble but is now made out of plastic type material and no longer a problem. after you turn on the water you start the motor and go from their. anytime you take off a mercruiser outdrive and place it back be sure to have the shifter in forward gear!like said you can get profession advice and info on this site; but you also need some mechanical skills.their are a few cracker jack wrenchs on here. willing to help. good luck and continue on. hope you get to enjoy what you paid for. another bad to the bone V20.
