E-TEC impeller change

Some time before next summer I probably should tackle my first impeller change on the E-TEC and I was wondering how long it would normally take if it all goes according to plan. I figure that it is probably an afternoon's work if it all goes well?

It is now about 3.5 years old, what's the probability of it going as per book and everything coming out without breaking off? The engine has been used in salt water but washed down after every use and never spent a night in the water, but I'm not sure if marine engines are assembled 'sensibly' or if they are like most road going vehicles where every bolt is wound in dry with no lube at all and then seizes solid.

Stephen,

Things to consider...

Setting the shift shaft height should be done when going throught this process, there is a video on the etec owners forum on how to make your own.

It may be a case of changing the housing as well if there is any sign of wear so do you have a complete kit to do this if needed.

The bolts that hold the leg on (x5) may cause some trouble if they have never been removed before, with all my E-tecs I have always removed and greased these then refitted when the engines were first mounted to avoid this problem.

I would allow a good afternoon for the job.

There used to be a video of the impellor change on the etec owners forum however I can seem to find it, there are some videos on youtube if you search for E-tec impellor change.

Did my F115 2 years after a shop did the first. No problems other than a broken piece the shop did (and epoxied to hide.)

Thanks, no hurry as it only needs to be done by about October. I'll look for the vid.

The original E-TEC impeller change video has gone. Barnacle Bill lost it as the server it was on disappeared and they lost the original off their computer in a flood or storm or something so while they intend to remake it, it would appear they haven't yet. Has anybody on here got a copy downloaded?

Another question: I got an impeller when I got the boat (now about 3.5 years ago) is there any reason why I should not use this part? Somewhere I have the complete kit, housing etc, so will use that. I have no idea what their shelf life is. It's been in a cool garage no heat or direct sunlight but I have no idea if they have a shelf life from the point of view of perishing etc - bearing in mind it's going to do a few years in there as well.

Also, I need to get a few bits including some gear oil and the pump you need to put it in with (used to have one but it went with the old engine). Ideally also some rib tube cleaner. Who's the best place to contact for a random order of boat stuff? I want it all shipped in one consignment to minimise handling charges.

I recall hearing somewhere that you should never use copper grease in marine engines so what's the best thing for the bolts? The most appropriate options seem to be graphite grease or something like a waterproof wheel bearing grease. I think somewhere I may even still have a tube of the genuine Evinrude grease left over that I got for the old engine, so maybe that is the best bet?

I did my 2007 175 without any issues, I did the impeller and gear oil and it took an afternoon relaxing and taking my time.

I use the blue evinrude grease when im doing anything on the etec - also used a dab to hold the key impeller key in place.

Scratch that, I just found it. I must have downloaded it when I first got the boat

I'll see if they want a copy back!

I can't host it or send it multiple times as it is 100MB and we have very low bandwidth and data limits in this part of the world but I guess if they get a copy back they might try and host it somewhere. It's 40 min long so can't be uploaded by a regular Youtube user. I'll post up whatever happens on here anyway.

Your replacement impellor should be fine if there is no obvious damage, The main thing with impellors when fitted is that over time they get "Set" in the bent position to the point where they have lost their flexibility and become less effective. The main issue with wear and tear on the housing is how much sand or muck has gone through the pump, you may well find that your housing is fine and the base plate also has no wear. However any sign of scoring on these parts and they should be replaced.

Mike Vincent from Southcoast Marine... he has it all in stock. Also I can liaise with Mike to possibly combine packaging with your new seat pad etc.

Use Evinrude Triple Guard Grease for bolts, steeering etc., Mike Vincent will have it in stock.
