2016 Craz 400 Coolant consumption
In 2017, my second summer with the boat, I got an overheat warning on my boat. I shut her down and took her to the dealer. Solution was it was low on coolant. Dealer added a gallon or so! and told me he let it run for an hour and never saw a leak. So the past 2 summers I keep a close eye on the coolant level. It “consumes” about 1 cup every 2 weeks or so. Is this normal? If it’s anything like my automobiles I never need to add coolant. What are others experiencing?

Quick addition to my thread. Owners manual says “ Check engine coolant “DAILY”! Failure to maintain the coolant at proper level can cause engine damage..... Does this imply Inmar knows these engines consume coolant??

You shouldn't be losing that much coolant, there has to be a leak somewhere. Do you have a heater? I think that's a common place to have a leak, and it would leak there even if you're not running the heater, the coolant is always circulating through it, at least that's my understanding.

Thanks for the suggestion! Looked at my heater box under seat on port side. 2 heater hoses enter the box and there was a puddle underneath. I’m going to tighten the clamps and see if that’s it. Unfortunately I already have the boat winterized so I can’t test it. Thanks again for the great idea!

I had the same problem. Leak at the heater. Tightened the hose camp and it has been good all year.
