    I recently took over ownership of this boat from my dad who passed away. This past weekend I rebuilt the engine. It was having problems when it was put up last summer with moisture in the oil. Those issues should be fixed (evac system and gaskets). Right now (No idea if it is correct), I have...

    I am looking for pictures of the parts I need, and the parts themselves. One thing off the bat I know I need is the cast thermostat piece with the multiple hose fittings. I assume the pump is a generic automotive short shaft.

    Just bought a 75 Southwind 20ft boat with a 460 and 12J/c pump. The previous owner was nor the sharpest knife in the drawer, based on a few of the issues with boat, but it was purchased dirt cheap as a project and things are expected. Doing a bit work on the pump right now, mainly sealing all...

    Ok so I have been racking my brain over this for some time now and wanted to get some input. I am a gear head, not new to boating or jets, but new to v8 jets. I am trying to get why you cant use a radiator. I have read arguments that state "no air flow to cool the radiator" or "exhaust will heat...

    All, looking to to double check my cooling system, I know there are a zillion threads but nothing concrete. I have a newly built BBC with 8-71, 5% under driven, nothing crazy. Running at low to moderate load I still watch the temperature creep up to 210, too high for my comfort. I ran my...

    Bypass cooling system not reading warm on gauge I am running a raw water system in my 383. I have this bypass set up. Polished Stainless Thermostat Kit For Chevy, 455 Olds The temperature sensor is in the intake manifold. The gauge reads cold (below 130 the lowest it reads) if I crimp both...

    Just curious if anyone has had trouble cooling their Olds 455 with a neovane pump. I took my boat out for the first time yesterday and got a little hot. After a 10 minute cruise, the temp reached just above 210 so I brought her in and shut her off. Let her cool for a while and tried again...

    Hey guys.. I am hoping someone here can possibly help with my question. I am building a bit of a different jet boat that I'm setting up so it can be run in salt water from time to time. http://www.performanceboats.com/jet-boats/108264-slickcraft-194-ss-project.html Because I want to set up a...

    I'm the guy that's been running my homebuilt water jet pack off my Berkeley. In the beginning of the testing stages this summer the first few hours we had no problems with air or seizure, just a matter of time, finally had a small seizure. I've been using the standard berk white ropes. Should I...

    Hey guys, I am new to the jet boat scene, and I just picked up a project boat, with literally no knowledge of what to do for the cooling system. Does anyone have a link or complete information on what to do for the entire cooling system? Any help would be appreciated. I have been searching...

    2005 Crownline 225 w/496HO. Yesterday boat ran fine. Hauling you know what down the lake and buzzer went off. Immediately checked gauges and shut it down. Checked fluid levels...All ok. Started it back up and ran fine to about 3/4 throttle. Buzzer went off again. Lower speeds no problem - system...

    I am running a cast iron mopar block. Aluminum heads. Reverse flow cooling (heads first). My question when I flush it what can I do to keep rust and corrosion down. My boat may set months at a time in a temp controlled garage. Can I run it full of 50/50 anti freeze or is there a better option...

    I've been running,adjusting, and timming the engine while on the trailer and sitting at the launch ramp. Question I have is,,,,can I cool the motor with just the impeller in the leg, or do I need both pumps. It seems that I have a lot of water delivery to the second pump. My system has water...

    I have a 455 olds. Single plane intake. And zoomie headers. Is it going to hurt the motor to run water in from the lake through the timing cover and thermostat and then out through the back of the intake ? I have looked at several different posts but I am more of a visual guy. I won't have the...

    Want to lake water cool. Engine has a jesel belt drive. I do have a teague belt drive sea water pump on it now. I used it for the lake water side of a heat exchanger. I am doing away with the closed loop (heat exchanger) system, too much to fail and it did. Can I feed the engine directly with...

    So I'm moving from jets to v drive and have a question about the water pumps I've seen. I'm building a 78 Sanger ski hydro and wanted to know the reason most pumps are cam driven? Is there a reason I'm not seeing electric water pumps being used? Besides the obvious ( water and electrical). Sorry...

    Hey guys im new to this site and jet boats. I have been drag racing cars for years and decided to try a new toy. 1978 checkmate with an olds 455 and Berkeley pump. I have a simple question. Can I pull water straight from the jet drive to the holes in block where the water pump is. Then use a...

    Ok, im not crazy about my cooling system set up. There has to be a neater way of doing this. I just made my new braided lines from my T Valve to the headers but the rest of my system is just plain ugly. Id love to see some pics so I can get some ideas. Thanks, Daniel

    I want to make sure I understand my cooling system. It appears to be a closed system. Marine Power 496 Vortec 8100 with Dominator pump. I do regular maintenance on this every year and have never done anything to the cooling system. Runs 150* all the time. Now that's this is 9 years old with 138...

    I have a v-drive and I plan on going to the next race at chandler, formerly Fire turd. I usually run a cav. plate pick up with a ron braaksma pump. I dont want to run that shitty water through my engine anymore so what is needed to just fill it with an antifreeze mixture and remove the pump for...
