Speedseal and 40/40 impeller replacement

Postby Craig » Mon Mar 25, 2013 7:33 pm

As most 40/40 owners know, replacing the impeller for the engine's raw water intake is a nasty job. I was wondering if anyone has put in a speedseal, and whether it has made the job any easier. I looks like it might let you get to the impeller with a little less difficulty.

I have a Speed Seal and it makes getting the cover on and off easier. However, it doesn't do a thing for getting the impeller out, which is by far the most difficult/time-consuming part of the job.

Is the impeller completely inaccessible in the 40/40. It's tucked on the port side of the engine, right? Do you have to take out half the boat to get to it? Any suggestions?

Just a follow up question - do you take the alternator off when you replace it? Do you take the wooden bench partition between the water tank and the engine out?Thanks!

You need to remove/move the alternator to get to the impeller. It's a royal PIA to swap it out and you NEVER want to have to do it with a hot engine. Get a pair of long handled 90 degree needle nose pliers at Harbor Freight to aid in pulling the impeller off. And yes, remove the curved piece of wood around the engine to give yourself better access.

P.S. As an aside, pray that you never have to remove the starter...

Thanks Geoff. That's very useful. We were just starting a week long vacation on the boat and were planning on changing the impeller, but decided to risk it. We Haven't had issues . Well do it when we're back.
