Hello all.

Can someone please enlighten me as to how to tell if these engines are FWC or RWC?

I can't see any reservoir for coolant.

This boat is kept in salt water at all times and a salesman is telling me that only the risers need to be changed if it's FWC.

I know it's a silly question but could make the difference on whether we purchase this boat or not.

Any help is appreciated.

a pic of the engines would help - the overflow can be hidden - look for the heat exchanger - if they are labled Horizon they are FWC

Here's a pic of the engine room.

We are in Florida so would be nice if they were FWC but I'm not seeing the hidden tank.

FWC engines require coolant so ask the salesman where the to add coolant...

Point being they don’t appear to be FWC engines and verify that with the salesman with one simple question.

I have same boat every 4 years complete replacement it’s raw water cooled so it’s salt or they will leak an seize the motor

 

[Ididntdoit]

Yup - look raw water cooled to me
