Thank you Monaco. I'm pretty sure we got the correct impeller housing but we didn't replace the lower half, which may have a bad seal. I might fill the lower unit while its off the boat and see what happens. After pulling it apart today, I'm fairly certain that the leak is in the lower unit...

Thank you Nassto.

Ok cool, we can handle that. What would cause the oil leak? Am I on the right track, replacing the oil seals? Thank you

After replacing the impeller and refilling with oil, I noticed that oil is leaking from the small water weep hole. My brother damaged the the nub on the rubber ring that went on the main shaft. I plan to replace that, but I'd also like to replace all of the oil seals as well. Can anyone point...

Thanks Iprof. What exactly do you mean when you say the flapper?

Thanks again, Spookeay. I went to another shop here in town and they sold me a Mercury Water Pump Upper Repair Kit 46-96148T 8 $56 w/ tax. The box says it fits all Mercruiser I/R/MR/Alpha One outdrives (s/n 2495186-0D469858) My serial is 0B880383 Do you know if it is necessary to pull the...

Is there any need to remove the entire outdrive to change the impeller & housing? I've found two different tutorials online. One says to just pull the lower part of the drive off, while the other says to drain the oil, remove the entire outdrive and put it on a stand. I would rather not pull...

Yeah, the stickers are gone. I'm fairly certain its an alpha I. Thank you for the responses.

Hi, I'm wondering how I can tell if my boat has an alpha or bravo drive. It's a 1988 Sea Ray Sorrento 21' S-21 closed bow. Any help is appreciated. Thanks

Thank you, Spookeay. I'm searching google to find prices for the proper kit, but there are many different options. How can I tell which kit is correct for my boat? I need to have an idea of what is a fair price because some of the shops around here like to gouge noobs like me. One guy tried...

Thanks for the quick responses, sorry I took a bit to get back. The problem I am having with the boat is that it runs cool at speed, but will overheat if idling or running at no-wake speed for too long. I'm planning to replace the thermostat and check the floats and springs in the...

Thank you

Thank you. I think The 140 is the way to go. I use the boat pretty much exclusively at Lake Mead (freshwater)and it is an open cooling system.

Hello, I have a 21' runabout i/o and I am wondering about which thermostat I should use. When I search I find a 142 and a 160 degree thermo listed as compatible with my boat's engine. I assume that you can run either one and people have preferences between the two for certain reasons...

I hope it works out for you. Owning a boat can be tough. I'm learning that with my first one right now. Ebay is a great tool even if you never buy or sell anything through the site. Best wishes!

Hello and welcome. Have fun on your trip.

Hi I just came across this site and found such great info that I joined right away instead of lurking around as I usually do with new forums. haha. I see that there are some great people around here and am glad to have found the forum. I recently inherited a boat from my dear departed Uncle...
