I have a 1992 GW Invader, 20 ft bowrider. 350 mag with 4 barrel, 21" ss prop. Engine was rebuilt several years ago, and starts and runs really well. Usually tops about 4400 rpm wot. The other day I was out with gps, and with 4 people onboard, managed 50 mph. Never really checked it before...
I am replacing the fuel pump on a '92 350 mag. The previous owner installed an electric pump, I am putting on the correct merc. mechanical pump. Where does the vacuum line off the fuel pump go to? It has a Weber 4 barrel. Thanks for the help,
Josh
I have a 13-3/4x21 michigan match in stainless steel. I am looking for a new prop for my 350 mag with alpha 1. My current WOT is 4400, at gps of 54. I haven't seen this particular prop for sale, but others like it are 14" or 14-1/4" in diameter. Will this lower my WOT? What stainless props...
I have a 350 in my '92 GW invader. It was professionally rebuilt last year. (Heads were not rebuilt). I am thinking about putting on the vortec heads and intake this year, but wonder if the compression will be too high with the new flattop pistons? Are their any other things I can try for a...
I have a 21' bowrider that weighs about 2900 empty. It is more like an 18' boat with a swim platform on it. It has a 350 magnum that is freshly rebuilt with high compression (10:1) pistons. It runs excellent. I think the gears are 1.50:1 and it has a 21" prop on it. The other night I had it...
I am trying to re-install a '92 350 mag into my boat. The alignment tool will not slide into the coupler. It appears that the coupler is too low. I did a little searching and the suggestions were that the rear motor mounts are shot. Is this correct? I assume the rubber is worn, letting the...
I am putting a 350 back into my boat. The alignment bar is about $120 at the local mercruiser dealer. I have an old outdrive, with a good shaft on it. Can I take it apart at the universal and use this shaft to align the motor? Or is there something special about the alignment bar? I've...
I recently bought my first boat, and shortly afterwards discovered it had a cracked block. I've decided to fix it, and found a block out of a truck of the same year. (1992) The motor in the boat was a 350 magnum. What makes it a magnum? I would like to build my new motor to the same level...
I have a '92 350 mag with a cracked block. I toyed with the idea of an auto engine, and still might adapt one, but found some reasonable prices on a marine long block. The newer vortec long block is the same price as mine. What differences are there? I know I will need a new intake, but what...
I recently bought a 1992 boat with a 350 mag engine. After one use I found out that it puts water in the oil, and its a lot of water. I suspect that the block is cracked. I've pulled the engine and am in the process of tearing it down. If the block is cracked, can I get a junkyard automotive...
I recently bought a used boat as my first boat. I am wondering which state to register it in. I bought it in new jersey, and the previous owner told me that jersey had an easy registration process, and I could possibly keep the registration numbers that are on the boat. I live in Pa, but am...
