The 500’s are so dialed in with temp and humidity tables, along with digital boost control, that they are not dramatically effected performance wise with ambient temperature. Short answer: no

Like Tony says, dialing in is about a lot more than the big hero number. We will generally use the top speed with each pitch of propeller as a comparative efficiency study. However, we want the boat to have the best manners from idle to top speed with a variety of weight loads in a variety of...

Hope you are well! We are doing some great things together over here.

Not in the modern era. They are heat cycled and broken in at Mercury. We warm them up then run them hard right out of the crates.

Yeah you can do it yourself. Whipple’s instructions are also usually very good. There is a bit of plumbing involved but nothing too difficult

Yes hard anodized head castings do make a difference in terms of inhibiting corrosion. For the OP, the edelbrock hard anodized marine heads would be a good option for the horsepower range and cost effectiveness. If you’re shooting for over 800, AFR is the way to go, sized appropriately for...

Put a medium thickness spring on the actual throttle cable at the carbs. As in the cable passes through the center of the spring.

I’ll volunteer for a what happens in 5 years episode. Promise it will be fire JT

Yes.

Agreed way too much cam, heads, and compression for boat use. Obviously it’s a bad ass NA race setup and could be turned down a notch or two in cam and compression and work in an NA marine race style application… but that still would be a long way from practical in a pleasure boat

I miss it too. Likely next time will be the DCB regatta, unless I’m there for a delivery of a new M37. We are balls to the wall setting up the new facility.

Your brother is not giving you good advice. Cruising at steady state low boost 4000 rpm is easy on the supercharger. Doing repeated pulls to 5000 under boost would literally be harder on everything in/on the engine. JT

Bought the exact same thing needed a backyard speaker for my new house in AZ

Running them full time could be a pain in the ass because the moisture in marine environment kills sensors, especially in super high performance that are on the edge of reversion etc… I would highly recommend installing bungs into every header or tail near the header/tail flange, then you can...

If the box is good, second most likely suspect is the module/pickup in the distributor

Thanks Jim. Hope all is well on your end!

Yep that’s me. Son of Bob. There actually is another John Teague in the industry at MTI. Unrelated, just coincidence. He was originally from Florida

Excited to be back where I belong 👍🏻

Not that I’m aware of at least.

That was the “prolong challenge” 😂
