leaking at WOT?
« on: June 14, 2009, 08:14:04 PM »
ok, have a 454 with a berkeley jg pump. new packing gland and transom sealed. at idle there are no leaks from pump or cooling lines. have a valve at inlet line and outlet, both are fully opened. problem at idle the motor heats up to redline but once going its fine. is this because there's not enough water circulating? and then when the water can get through the headers it flows more? other problem is when not at idle (usually above 3000 rpm) there is a leak coming from somewhere. and its a pretty good one. my guess was a hose or something leaking when theres more pressure but I can't find anything wrong. any help....its driving me crazy. nothing like letting off the throttle and have a river come down the center of the boat. thanks for anything ya got

Obviosly you're running OT headers. How is the thing plumbed (Pics please, I went through every thread on this site when I did it, and still started a new one, easy to mess it up) and is this a new problem on a proven boat or a new (or rebuilt) boat that has this problem?

What size hoses are connected to your motor from your pump. You may not have enough valume of water to your motor due to small water lines, like -6, -8, at low rpm. also check your thermestat.  sp, if you have one. Is there a bypass relief  valve in your cooling system. jet pump at high rpms put out tons of water pressure. If you using old style hoses like heater hose, there not rated for high pressure and or have a cracked hose on that only leaks when the pressure builds up.

oil is clean, no water present. it doesn't make sense to me how that much water can get in the boat without a leak at idle.

Your avatar pic could explain a lot??? Are you sure the water is coming from the engine?

Line sizes are the last place I would look, I'm thinking you have a pump issue. Is the bowl gasket inside the boat?  :sly:

Pics are worth 1000 words... :thumbup:

yeah bowl gasket is inside the boat....haven't thought of that one! and i'm sure the leak is coming from the engine/pump. i've gotten pretty good at fiberglass work haha. i'll try to get some pics next time i see the boat.

Taco'd "a person or people that show up with one lake lice and a family of 50 and cram 3 people at a time on it with no disregard to boating rules or ethics. Usualy crap in toilets and throw shit paper in trash cans. Hang out at the boat ramp like its a swimming hole. Have zero insurance on anything they own and dont give two shits less about your property."
