Sand eats them up pretty quick. Also make sure you NEVER run it without a water supply. I occasionally check mine and have replaced it a couple times. Truth is I've never had a "bad" one. Even the ones that were 4 or 5 years old still looked fine. I replaced them anyway. My boat is a 1990 and it's had 4 impellers and none of the old ones had anything significantly wrong with them. Merc just advises every year to cover their own asses. If you couldn't get it into reverse that probably means you did not have the shift shaft lined up properly. It's a splined shaft and is not keyed. It is a pain to hold the prop engaged while getting the lower half on to make sure the shifter is in the right spot. But there are a number of reasons to be competent at removing the outdrive like occasionally greasing the u-joints. I usually take mine off every other winter, check the impeller, grease the u-joints, and replace the gear lube. On the odd winters and occasionally during the summer I "sample" the lube at the drain to make sure it still looks good and doesn't have any water in it. If you really don't like the pump in the outdrive you can get a engine driven mechanical one. That's what the volvoes and bravoes have. There are a lot of boat scrap yards down there where you could probably dig up the brackets. Sounds like you might not have an electric pump that is up to the prolonged cycle you are running it at. That will be a real pain if it craps out on you. A mechanical pump is less likely to completely fail like an electric motor. Nothin personal but I'm going with "bad idea" on your electric water pump.

And you do have to replace them every year.

I was able to get a puller & inserter on loan from Autozone. The old stator came off pretty easy. The magnets however were all busted up, and I had to carefully look around for loose pieces. When it was all setup and done, the kit was well worth it. It came with the brackets, bolts, washers, belt, and wiring harness, along with a step by step full illustration.

Sorry if that's what I implied, not really what I meant to say.- Hide quoted text - - Show quoted text - Throttle body is kind fo neat , that is on a car, but look at all you'd have to do for a boat. High pressure fuel pump, computer timing etc, etc. It HAS been done, but it's not worth the cost of a change over..... BTW, i know exactly the the alternator kit you used. and with the exception of making the brackets. The alternator is only about $55-65.00- Hide quoted text - - Show quoted text - So you used an electric water pump to replace the raw water pump in the outdrive? What prompted that? Laziness for the most part. It is a pain in the ass to drain the lower unit, unbolt it, remove it, replace the parts. I tried doing it myself once. I followed the step by step directions in the Clymer manual, but I screwed up and now the boat doesn't go into reverse. I ended up hiring a mobile marine mechanic to fix it right. Now that I have the electric raw water pump setup, All I have to worry about is replacing just the lower unit gear oil every season. An electric pump take me 5 minutes to replace, and it costs the same as an impeller kit. Jim Rojas- Hide quoted text - - Show quoted text - Ingenuity is good. But one thing I must question. I know the kit you bought to repair your charging system. It' is expensive, but it does work, fit and is professionally made. and you gave $400.+ bucks for it and thought it was money well spent, which in your case probably would have been, because trying to mount an external alt. on that engine would be a PITA. i can understand that. But wouldn't repairing the water flow system follow under the same notion? Pay the money and have it fixed right? |
