    Help me set up my new edelbrock 1409

    8 degrees keeps the motor dummy proof from someone using 85 octane fuel with water in it (detonation) and keeps reversion at bay when when the motor is installed in a sterndrive application with a lot of tail load (extended swim platform). the distributor advance of 24 degrees makes the motor...

    Volvo Penta 5.0 GL PWTR - severe overheat - thought I was on fire - troubleshooting Questions

    lack of cooling water is why you overheated. key off and anchor awaiting a tow would have been the best COA when was the last time the raw water pump was serviced? 1- could have a thermally broken block or heads, could have taken out the bearings and collapsed the pistons. all the rubber...

    Crank driven vs block mounted raw water pump pros/cons

    I use a crank driven water pump as they are standard on VP engines. you can go up in size with them as well. makes changing impellers easy. and removing sediment when you bury the outdrive because you are in skinny water.

    I have concert Tees older than the crew at my last job. New position I got to staff with a few grey-beards that have worked for me in the past. Our little group of 4 puts out more new products than the group of 20 folks in the new product group on the RV side

    Brake woes

    that is not even broken in yet...... have you priced a new truck lately? regarding the calipers. did you clean out the debris from the clips on the pads? that will cause them to bind a bit. did you service the slide pins? the grease in them gets hard and the slide pins quit sliding.

    Options to repower a 33' Larson

    I wouldn't go down in power or drop down from the Bravo to an Alpha Two 502 BBCs, or two 6.2s, or two 6.0s or two diesels. Big hulls need torque. 4.3 or 5.0 won't cut it. A pair of supercharged 5.7s maybe. If you're wanting to go carbed, I would most likely build two 6.2 aluminum LS based...

    Bought Boat and Steering is locked up

    Last two helms I swapped, not even a 3" bore hydraulic cylinder at 3000 psi could budge the core in the sheath. That is 21,000# of force. Rust is strong

    propeller doubt

    the motor cares that it can go to full RPM. Do not lug the motor, especially on a new rebuild. that will kill it. what ever prop pushes the boat to WOT RPM of 4800-5200 RPM is the prop to use. on a boat that big with a 4.3, most likely a 13p or 15p. the 17p prop you have is probably too...
