its it a slip at the marina currently. i can watch if flow great up to 1000 rpms steady. not till its under load with more throttle does it stop. I was gonna bypass the cooler go right from the raw pump to the tstat housing with a clear hose for a test to see if it keeps flow.
The clear hoses were an idea from a shop . The issue was first the boat wound hsve good temp at idle then running drop to no temp then climb to hot fast . They said try the clear to see if you have an aeration issue . Which let us see the flow stop totally . It’s a new impeller , circ pump and...
Compression was close across all cylinders. But all good numbers .
I’m just confused how the flow totally stops but dropping into neutral and revving the the throttle brings it right back . I would think a little sir would cause bubbles not complete stoppage . It’s super weird
I meant the belt is tight . I will try to run a clear hose from the cooler up tonight . I priced the pump at 500 which isn’t horrible if it’s what’s needed . Just have never gets if one going bad . And it doesn’t make any noise or leak in any way . If it’s driving the fuel pump as well and I...
No worries man thanks for tryin to help
no strainer, bent is tight . Not sure on it being serviced it’s a new to me motor this season . It’s the pump with the mechanical fuel pump mounted on it . What service needs to be done ? Should the whole pump be replaced ? Thank you !
we put clear hoses on from the tstat to the riser. once i throttle up the pressure goes away and the hoses have zero flow. if i pull in neutral and rev the motor flow comes back up strong
the hose from transom to seawater pump is new and soild type hose. That should be only suction correct? the other side out to coolers and motor is all pressure push.. thank you for getting back to me
riser are a year old and clear as can be. I have good flow through the cooler no pieces or blockages. its the dual oil and steering cooler. its fresh and some salt.. mostly brakish water .. It has super strong flow at idle and slow speed. up to say 1500 rpm, once i start to get into it flow...
i have a 1996 carbed 502 in my 1999 baja 232. at idle boat has great water flow. once i throttle up to get under way i lose total flow to my risers. This was confirmed by running clear hoses to risers from tstat housing. New impellar,circulation pump as well as thermostat. Riser are good and...
