Greetings, again while powering across the lake at 45mph the coolant hose from the thermostat housing to the impellar pump housing on the engine blew and spewed water all over...thankfully since this happened i always carry a spare hose....this is getting annoying now, and is ruining the time on the water since it's spent mostly worrying instead of having fun....Heres the quick history...
the first time i had no clue what happened so i just replaced hose...a few times out later the hose blows again and get stranded and towed in....sucked so i was told there must be a clog somewhere, i rip all the hoses off to find the clog, and i did...there was a clog from the line that goes to to exhaust riser from the "T" in the line that comes directly from what seawater pump (the t is the one part that goes to thermostat housing and one part that goes to the exhaust riser)....this hose was clogged with a piece of old seawater pump pieces....apparently the previously owner blew his water pump and sent pieces through the system...btw, i have a NEW seawater pump installed since last year (the first time this happened since i thought i had blown the pump but it turned out to be good and not missing any pieces off of the impellar...) so anyway about a season of boating passes hassle free, and BOOM now it happens again.....i'm lost?!?! i removed all hoses again and found nothing clogging any of the lines????? this time when i did replace the hose and idled back to the dock 30 minutes the engine ran steady at 170 degrees or so....
ideas???? here is a pic of my setup direct from volvo site with notes......
