I have recently installed 2 28hp beta's in my catamaran. I did not think about the optional water heater connections when I ordered them and I am curious if these can be still be made at this point.
Of course these fittings can be retrofitted to either or both of your engines. Please call us at the office (or email) or speak to the dealer that you purchased the engines from and let us know the actual spec of your engines. We do keep all these fittings in stock.
