Been running my 96 SeaSport alot this summer since purchase in May. I am tickled to death with almost all of the features and the way she handles. One problem that I do not understand and have not spent time looking into yet is the heater.
This is an Acuheat system running off of the engine block.Fan and heat exchanger are located in storage area under cuddy cushion. Two hoses running to form the loop just like the heater in your car is set up.
Problem I have is no heat at idle and low speeds. I have to start working her over 1600 RPM's to get things hot. Then it works great.
Guy I bought it from said he changed out factory 160 degree thermostat to 180 for more heat. Works great when she's got a load on, but cools quickly when down to idle.
I also have an Almar riverboat with 351. Virtually the same set up and distance from engine to heater and it pours out tons of heat at idle all day long.
Anyone out there got any clues as to whether this is how it is supposed to work, or can I do something to get heat when idling? Advice and tips are much appreciated.
