Hello everyone. New to boating. Picked up a 79 Hallett Jet boat on saturday. Built Ford 460 the guy went on and on about upgrades during a recent rebuild. Berkeley pump. My concern was the temp. When i was waiting for some people to join us i noticed my temp went up to 240. Oil pressure was pinned out at 80. I didnt notice the running temp when i took it around the lake. Does this sound normal?

Should never run that warm , double check your line coming from the intake. Is there a valve ? Make sure it’s open !

240° is not normal.
With logs and snails, 140° at cruise, and 160 tops in the no wake zone.
With open headers, 125°-130° is fine.
This is without a thermostat.
How is the cooling system set-up?

Check to see if it has a gate valve/ ball valve . This is located to the right at the bottom of the hull looking at stern of the boat from inside check to see how far closed it is . U will have to adjust it when running to get the temp u want . That is the first thing u should look at

Give me a sec to learn the site i may do better on my computer. Responding to everyone. I haven't looked for a valve yet. But i will im also asking the PO more about the setup

Does anyone have a pic of where the in and out is for the cooling and an example of this valve im hearing about

It’s normally on the inside of your boat, location near or around your pump. Its looks like or is a water faucet valve. Hint the more you open it the cooler it runs, and the more you close it the hotter it runs.
