    Ideal Mercruiser 350 cu.in. running temperature?

    New 350 Chevy engine with about 400 HP. Running terrific but water temps seem to be too hot. Gauge reading 190º at, say, 3500 rpms. However with my hand-held LED thermometer I get readings of 125º-145º taken from the thermostat housing, the manifold, the engine block and the risers. Thermostat...

    INBOARD marine 350 Chevy running too cool!

    Subject: my fresh marine Chevy 350/375hp in the 1977 Aquasport 222 Osprey. Raw water cooled engine is running great, but temps are in the 110° to 130° and it takes forever to warm up. 140° thermostat. It will get up to 140 on the gauge at, say, 4000 rpms, but in my mind not fast enough. I think...

    Quadra Jet: cross threaded fuel intake fitting

    I managed to cross-thread the Quadra Jet male-threaded fuel intake fitting. Of course it leaks. The brass fitting male threads look good, the carb female threads not so much. If I tap out the intake housing, I assume the male fitting will no longer fit properly (?). I'm not sure if it is a...

    Raw water pump-can you identify?

    Center console w/350 SBC was built in 1977. Engine replaced, but the raw water circulating pump probably original. I want to replace impeller. Model plate on back of pump can't be read. Can you identify so I can order an impeller?

    Installing skeg on Aquasport Inboard

    My 1977 Aquasport CC 22-2 Inboard — 350ci/370HP Chevy— has lost it's large keel/skeg. As you can imagine, with this boat the big skeg protects the prop and prevents sliding when turning. She steers straight but slides/drifts. The skeg was damaged banging repeatedly on a hard sandbar in a raging...

    Dummy Left Seacock Closed

    1977 Aquasport 222 INBOARD. New 350 SBC/ 375 HP long block. Marina put boat in water with intake sea **** closed (flush position) and upon leaving marina and running at low RPMs for about 10 minutes, I noticed temp was at 230-degrees F from lack of seawater. Temp did not peg at 240, but stayed...

    Desperate: Early sbc crank pulley

    Attached photos show a 3-groove crank pulley from my 1977 5.7 sbc in my 222 AQUASPORT straight inboard. The pulley is cracked significantly around the outside v-groove that drives the water pump. The inside groove drives the alternator. Center groove is not used. Opinions from some trusted...

    Aquasport 22-2 INBOARD needs crate engine

    Now I've gone and done it to my sweet 1977 Aquasport (Inboard). Bent a few valves in the early Chevy 350 (compression check with the distributor out?!) and think it's best to get a crate engine. Want more power anyway. I'm looking at Chevy marine 350 and 383 strokers ... but there are so many to...

    Lightened boat, same speed?

    So glad to be a new member of this forum. My recently purchased 1977 Aquasport 222 has a "marineized" 350 sbc and I was told is a 300 hp. Good luck! With a dual-control full tower it would run 18 mph @ 3,800 rpms. To gain more speed I removed the tower to get the weight down. Now it runs the...
