I have a Hunter 45cc. My generator is mounted forward of the engine and does not allow me to remove the core of the heat exchanger without removing the exchanger housing first. I am thinking of cutting the core in two sections which will allow me to remove it for cleaning without disconnecting the housing as well. Reinstalling the core I could align the tubes with a rod and then close the end cap. Has anyone done this?

How often do you expect to do this?

Why not relocate the exchanger when you take it out for cleaning. There is nothing sacred about the location as long as it gets engine coolant and raw water coolant. Just don't go nuts and mount it 3 feet higher and 10 feet away

What is the brand of your Generator?

My new one is Kohler.

But...

Although a Pain to remove, it can be done.

Why do we even bother to repeat this :

You intend to cut THIS in half :

.................. and then what, tape it back together, wire it back together, buy a new one because it was a lousy idea to cut it in the first place ?


With a few photos:

Firstly, we could get a picture of WHAT you intend to cut in half.

Secondly, maybe we could see a better way of removing the heat exchanger.

There is a whole slew of engineers, mechanics, and very experienced individuals on this site who :

DON'T HAVE YOUR BOAT ! ! !

................ so cannot offer their expertise without seeing what they're dealing with.

As we always say to people who don't include pictures: "Help us to help you."

My generator is mounted forward of the engine and does not allow me to remove the core of the heat exchanger without removing the exchanger housing first.
And lastly of course : is this the generator hex or the main engine hex?
