anyone heard of high flow thermostats?

[bob johnson]

before i try to gerry rig a standard T-stat, id figure id ask if anyone has seen or heard of a high flow thermostat.

I know my motor could use one...it needs just a little more cooling...

one head runs to 190 some times... i think it might be when i have my jack plate raised all the way up...

but since i use it in that position alot , I figure Ill try to address the chance to get more colling through the head first..

thanks

Re: anyone heard of high flow thermostats?

You have the correct waterpump? Correct thermostats? The thermostats were upgraded, not sure what year. 190 too hot. High speed water pressure pushes thermostat off of seat and bypasses thermostat. Install water pressure gauge, if motor too high pressure will drop.

Kit number for later model thermostats. 435597

I have the correct water pump( just installed)... but since i have a water pressure gauges and am running 10 psi at idle and up to close to 30 PSI at WOT, it wouldnt matter if it was the right one or not ha ha

thats good water pressure!!

the thermostats are brand new, and they look just like the ones that came out...

they are incased in a hard plastic housing, that i think restricts flow....

I certainly know 190 is too hot, and I am trying to address that...the motor will run about 160-180 most of the time but in cruising range it spikes 3000 rpms-3500 the water temp rises in the port head...


this weekend I am going to monitor the jack plates height in relationship to the temps..to see if there is a correlation..

but id still like to try some high flow t-stats
