Hi everyone, I have been a marine mechanic for 26 years. Would love to help any that I can some of the newer guys (to boating) with tech. questions, especially on Vacuflush.

Just fish around....you can find lotsa friends here....nobody seems to flame...I am a "wrench" myself and have learned a few things while perusing....there is a wealth of knowledge/opinions here.

[hooked on water]

Dear Brad

Thanks for your offer
am about to fit out a 32 foot ferro hartley
interested in fitting the lister diesel to the boat shortly, but am intrigued as to whether to fit fresh water or salt water cooling to the engine.

I would appreciate your views on this matter, and anyone else while we are at it

thanks again

Hooked

[Alan Wheeler]

What size Lister do you have there Hooked??
Has the engine been "Marinised", or do you have to fit all the equipment for such??
It is certainly more benificial to the engine to be marinised, but if it hasn't been already, then it is also expensive to do so.

Dear Alan

The engine appears to be marinised, but will get back to you with more detail on it in a few weeks

It looks the same as all the other marine motors I have seen over the years

Gear box is fitted to it although I am contemplating getting it overhauled before fitting it - be sure they say

It is a 26hp

cheers

OK, then an enclosed fresh water system is far the best.
A marinised engine will have a heat exchanger that cools the hot engine coolant via the colder seawater. It will most likey have a water cooled exhaust maifold as well, although this can be found on either types.
