Two weeks ago the cabin heater stopped heating and hot water heater wouldn’t produce hot water except when plugged into shore power.

I will pull the heat exchanger when I’m back my homeport and change the hose clamps. Since this is about 10 hose clamps I’ve found broken, I presume the hose clamps originally installed we’re not lifetime hose clamps! I will order a new set and replace every clamp.
Before oil level is exactly where expected for this number of hours. About 1/4 inch below the full Mark. Good idea. Thank you. [links]

From my previous post: My curiosity got the better of me and I called Seaward. The company was sold to Attwood 3 years ago and the tanks are now being produced in MI. The person I spoke with stated the engine loop is a double lined loop, both loops would have to corrode for coolant to enter the the domestic water and the smell of engine coolant would be noticeable at the faucet. Average life of the units are 10 years.
Appreciate the replies. I'll check the level with the valves turned off for a while, and then turn them on. It is definitely important to make sure the HWH is definitely the culprit.
I should clarify slide forward is into the compartment but it towards the stern it comes out here

I have a switch for the hot water heater on the 120 side of my breaker panel. I have tp turn the breaker on before mine will heat. I only use it when I am connected to shore power, so I don't have any experience about using it underway. more
Are you asking if the water heater comes on while running the outboard? If that is your question, then no, the outboard will not transfer heat like the inboard diesels do.
A word of caution. My water heater gets the water scalding hot in as little as 5 minutes and, if I have one, I have no idea where the temperature control for the heater is - other than to put the faucet handle in the desired position. more

Interestingly, our most recent move back to diesel - likely a permanent move - was prompted by none of the issues touched upon in this thread. Namely: here
Of course the outboard R-23 and new 2018 R-27 models can reach top speeds of around 40 mph whereas the R-25SC and R-27 (Classic) cannot reach these speeds, so fuel burn rate comparisons above 20 kts makes little sense.
From my research the fuel burn rates are quite similar for comparable speeds. Thus the comparison would need to be in the range of 10 to 15 kts as the R-25SC and R-27 (Classic) at these is the likely cruise speeds for the inboard diesel models.
1) Safety: gas is highly combustible and diesel is not. Never even gave this a consideration until we realized the clear liquid accumulating in the bilge of our SeaRay was not water but gasoline. Turns out that our 8 year-old SeaRay developed a hairline crack in the fuel tank. Note also that the pounding that a boat takes is far greater at 30-40 mph than at 10-20 mph, and I've learned that leaky fuel tanks are not as rare as one would hope. We were just one spark from our batteries or inverter (just inches away from open gasoline) from a deadly fire or explosion. Whether I would go back to gas is now a moot point - my 1st Mate, Peggy, would not even consider it! [links]
2) Cruising Style: the problem with the SeaRay was, as a planing hull, it handled very poorly at slower speeds when sea conditions were rough, or when logs were prevalent in the water, not uncommon where we boat. I found that running the SeaRay anywhere close to WOT (30-36 mph) was white-knuckle driving, in direct conflict with my goal to seek relaxation when I boat. And running at slower speeds was uncomfortable at best due to poor handling characteristics. here
