Ron, literally thousands of us have this installation. Not an issue, but a reasonable possibility from pure forensics.Engine water pumps only push so much water so far. Maybe you need an aux pump to move all that water that distance?

Not necessarily. I have a 6 gallon Kuuma that came with the boat. Same problem you have been having. Slow to heat water with motor. Replaced it a couple of months ago with the same hoping for an improvement. I have not seen a big improvement. You are not the only one.The case on my original Seward 6 gallon rusted badly and then the tank developed a leak. I was hoping that the Kuuma would hold up better because it has a stainless steel case and uses the same heat exchanger design. There are several other boats on my dock with the same Kuuma that heat up very fast so it is a personal problem. {sigh}
Apparently what Kuuma engineering “feels” is not what is experienced in the real world.jssailem, Kuuma engineering tells me... They feel that the process of bending puts enough of the two pipes into contact to transfer the heat by metal to metal contact...
The heat exchanger in a horizontal loop water heater is not directional the inlet is the end that receives water from the engine and the outlet returns it. If the exchanger loop is vertical there might be some gain to one orientation over the other but I do not think it would be very large. In a vertical coil exchanger you would typically have the inlet at the bottom to supply the hottest fluid as low a possible.I have this same issue with my 11 gallon seaward... just doesn’t heat up quickly. So this coming weekend I am changing fresh water coolant and all hoses. Here is a question (maybe dumb)..... is there a specific way to hook the hoses up? I mean does engine hose “a” have to be attached to water heater inlet “a” to have it flow In a certain direction?
That is a nice unit and with a 10' long exchanger it should certainly heat quickly. Cost of over double of the other three so I might need to do some talking to get that!If efficiency over cost is a consideration, look at the Quick Windlass BXS2512SL. It is a 13 by 13 unit. I am happy with mine.
That is where I checked and with my Oak Harbor discount the BXS is $660, Seaward SS is $330 and Kuuma is $240.Check out fisheries supply in Seattle.

Hayden, I got a Seaward at Sure Marine for $260 + s/h in 2013. You can do better. Google internet shop. I don't think they sell them here, but try, too.Look for value. If the Kuuma doesn't work you're not getting much value for your $240
