Impeller Replacement - Engines & Genny - Cost $ Estimate?

[SkippyzAfloat]

Hey everyone,

As our '00 340DA is relatively new to us and the previous owner had no idea when it was done last, I've decided to change all of the impellers as a relatively low-cost preventative maintenance item. Does anyone have an estimate as to how much this may run in parts/labor? Engines are 7.4's w/V-Drives and the genny is a 5kw Westerbeke. Is this a DIY-able project for someone that is relatively handy? Any special tools/tips required?

Thanks!

Simon

When winterizing my 240DA two winters ago I've faced an issue with poor water circulation, which was result of bad impeller. I never did this job before, but I consider myself a very handy guy. This was bad time since most shops were booked with winterizing projects and I didn't feel like paying top dollar for emergency repairs. So, I’ve purchased the impeller from local MM for less than $100 and replaced it myself. If I recall correctly, it took no more than 1 hour. The only difficult part was getting to the unit, it was not easy to access, but I was able to manage wit no issues. I would imagine that it’s not any more difficult for genset. So, my answer is YES, it’s 100% DIY, but it all depends on your comfort level and if there’s enough room to get to the units. I would guess that dealer wants about $250-$300 for each. I’m sure you’ll get exact figures from other members.

Good luck,
Alex.

My experience: the genny impellar runs around $60 from the local SR dealer. Friend had to replace his, took probably an hour.

I had the impellars on our 320 w/6.L V-drives done by the dealer, $704 total bill. I watched as the mechanic did it and I doubt I would ever consider that a DIY project. If you have stern drives the impellars are much easier to get to.

On the 2000 340DA with 7.4 V drives, access is the biggest challenge. I do and have done all maintenance on all boats I've ever owned, but after the first bout with the impellers on the 340, I paid someone else to do it. If I remember correctly, it was about $500-$600 for 3 impellers + labor. So, unless you're a pygmy contortionist, I would recommend fixing that one with your wallet.

The genset is relatively easy and only took approx 5-10 minutes, I replaced mine last year, same gen and total cost was about $30.

I agree, access is your biggest challenge here. It's not a tough job once you get to it, and hopefully can get back out!

With my back and now 2 bad knees, I pick and chose my engine compartment battles wisely now.

I have a 2000 340 also and changed the engine impellers. I wrote everything down that I did to change them, socket sizes, tools needed, and what I had to do to access them (the hardest part of the job). I have these instructions available and can email them to you. I am 5'11" and weigh 170. If you are much larger you are better off paying someone to do it, but it won't be cheap.

Thank you all for the input!! I was hoping that the job might be relatively simple, but it's sounding like as Pirate so aptly put it, that I should fix this one with my wallet. At 6'1", 275lbs, I in no way fit anywhere near the pygmy classification, so I'll have to either look for the circus to go through town or bring some coffee and donuts in to the marine mechanic's and start doing some serious sucking up!

Thanks, gs65jgs, I'll PM you as I would at least appreciate understanding the process so that I don't get taken to the cleaners!

Cheers to all!

Would anyone happen to have a step by step for a '98 270DA?
