FWC normal operating temp

[FreeBeeTony]

OK....I tested the boat on the water today after repostioning the H/E today (see earlier post) The boat ran perfect, temp didn't continue to rise as before. The temp seemed to top out at ~180. This was running at 3000rpms for a while. When going through a no wake zone, the temp was at ~150. I have a 160 deg thermostat installed. Is 180 OK? Or is this still too hot? I am concerned that when the water temp in the bay warms up the engine temp will rise also. The bay temp today was ~50. When the bay temp goes to 60 will my engine temp go to 190? If I use a lower themostat will the 180 go down?<br /><br />I'm almost there! <br /><br />ALso, I added an overflow tank. When the engine warms-up the fluid rises in the overflow tank, but when it cools down the fluid doesn't return to the H/E. Could this mean that the system isn't air tight and it's "sucking" air in from someplace? I have a 7lb cap on the H/E.<br /><br />Felt great to be back on the water running again........even caught a few flounders!

Where'd ya catch those flounder? I was in Raritan Bay today, didn't catch a thing! <br /><br />Sorry, can't help ya on the temp issue. I have a FWC system, but I have no T-stat. I run about 140-150 all the time.

Caught the flounder in Fire Island Inlet, near the Sore Thumb. I did a search on the operating temp, it looks like I may be right on target. Still wanna hear from some of the guys on here for their opinion.....<br /><br />hey bondo.......

Hi Tony,<br /><br />Yep,<br />I Think you're on the way, <br />To Where you want to be.........<br />180*, Should be Fine........<br />Even 190* isn't Bad......<br />Water Boils at 212*..... Your Good till Then......<br /><br />My Guess Is,<br />In the Newer style Auto-Recovery type systems,<br />The Cap seals on the Top of the Cap-Neck, allowing the fluid to return to the system, from the overflow bottle........<br />The cap-neck on your's Might be sealing on the lower flange of the neck, Rather than the Top Lip......<br /><br />I don't know if you can get it to work right or not.....<br />The H/E Doesn't Have to be Full, To the Top, when Cold......<br />Just leave enough room for the Normal Expansion........

Re: FWC normal operating temp

thanks bondo.........<br /><br /> So in order to get the fluid to go back into the H/E, I may just have to change the cap? How can I tell which cap I have? I just bouth it at Auto Barn.<br /><br />What about the increase in the raw water temp?<br />Will this cause the cooalnt temp to rise?

Not Sure Tony.......<br />I Do Know, It needs to Seal on the Upper Most Lip.....<br />

What about the increase in the raw water temp?<br />Will this cause the cooalnt temp to rise?

Maybe When the Ocean Temps get up to 190*, or so.............. <br /><br />If You're That Concerned,<br />Go to a 140* T-stat..........<br />I Think It's Right Where it Should Be.........
