I installed a 7.3 Kohler in my 357.

Here is my Big Brother and Little Sister

Are those bilge heaters?

Thanks for the pics.
I'm thinking of the same idea of twin boats. I have the matching 242LS of a 357 SR1 that I could buy. Funny that the graphics are the same Palm Beach graphics you have.

Those pics are exactly what I needed to give me a feel of space. The problem I will have is that this 357 has TRS drives and the engines are about 12" forward of yours. I think that will force me to use some of the space under the back seat in the same manner of the 382 and 353 with gen sets.

What is the smaller boat?
What speeds do you see with your 357?

I had a 357 TRS with gen mounted right in front of both engines... it fits!

I have a 357 there is plenty of room for a gen install I front of engines only will make port water pump a little tight for service. I do t have a gen but am a marine technician and have installed dozens. I boat up on the Lake Erie islands lots of beach time and time with no shore power I rum 4 group 31 agm batteries and have no problem if I was you I would just install an big inverter or a 12v AC. Any question feel free to give me a shout leav a voicemail if I do t answer 419 6564882

The Kohler is waaay better than the Onan installed from factory in that vintage Formula.
Good call...

That pic you posted, over in drives section, looks like the gen is completely in the bilge and does not reach into the rear seat. Am I seeing that right? If that is the case then there is far more than enough room in front of the TRS installed engines. I like knowing a gen will work.

Now we'll have to see which boat I get.

So the 357 had some factory Onan gen installs? I was going to go through the brochure again to look for that info.

I'm told the the Kohler is a little bigger and louder than it's counterpart Westerbeke. Either one is ultra low emissions so I guess would go with the best deal I can find. I do like the Kohler product pretty well but as I understand Westerbeke has been into marine gennys longer.

I am not sure on the 357...sorry.
I have a 1993 419SR-1 and the original install is a 3K Onan.
It is less than stellar in the noise and power output. But because it was already wired through my electrical panel in the cabin and set up for the Onan, when I replaced it I reinstalled the same Onan genset.

The Genset is well worth the headaches to install if you can get it done
