This 1996, 17' Crestliner Sportfish was my Dad's and has been having sporadic overheating problems for as long as I can recall. As far as I know, it has never been in saltwater. I inherited it last year and it ran good for the first few outings, but then overheated. No pressure to the hose running into the thermostat housing. I replaced the impeller which had missing splines. I believe I chased down all the pieces which went as far back as the power steering cooler. It ran good for a couple times then back to overheating. I replaced the thermostat to no avail. I noticed a weld was broke and leaking on the power steering cooler so I fixed it but to no avail. I can blow air unrestricted from the PS cooler back through the thermostat and raw water pump. The firt time i tried blowing air from The PS cooler through the intake port it seemed like there may have been some blockage. I ran water back and forth from the PS cooler to the intake and it seemed to free up. I can get water to feed up through the intake to the PS cooler only if I hold the muffs down really tight. I can get the motor to stay cool if I prime the raw water pump by first holding the muffs tight. It will not prime otherwise. Perhaps a crimped intake hose in the lower unit or something along those lines? Re-check impeller? Risers? I am a novice auto mechanic at best and I am at a complete loss and feeling more than a little beat up after losing the first few rounds to this I/O. Any help is greatly appreciated.
