"Marine grind" is not really the right term, "marine grinds" is more to the point. It's like saying "car grind" there are as many different applications in boats as there are in cars.
My boat is small at 16 feet. Planning hull. Relatively light weight. Two person only. No skiing, no towing. Vintage speedboat for mostly flat water, lake and river boat.

It's style of cam would be different to a 25 foot 6 person ski boat. I don't need the low end torque to dig a heavy boat out of the hole and onto the plan while towing a skier.

Speaking of antique boats, this has been advertised locally when I search for "flathead". Years back I saw one at a guys place up north with a Chrysler 413. It was a masterpiece of woodworking.

Taking shape... Worked on mounting the spark arester tonight and working out the in and outs of the expansion tank. Still got to shorten the spark aresster for deck clearance.
Looking more like a motor every day.

How about oil issues? I would think that the rear rods/crank throws could be hitting the oil in the pan. Also would have some concern on the oil pickup becoming uncovered. Might want to consider some baffles of some type for the pickup. Looks like a good candidate for a dry sump!

Yes good points. The first step at least will be bending the oil pickup to be parallel to the bottom of the boat. Next step if needed will be extending the sump, keeping the same point where it's deepest and going forward and back to get more volume and a flat pick up area and to lower the oil height away from the crank. Just not sure what is needed yet.
The engine is only at 12 degrees so some roads would be that steep.

ON our Hydro engines I mad some adapters for the carbs that leveled them. I also used 2110 carbs so I had to bore the throttle bores out abit.
