I'd figure swapping for compatibility to have a cast iron gear sounds good. GM HEI distributors had/have open vents in the bottom of the housing that don't have the appropriate spark arrestor screens and the area where the lever from the vacuum advance mechanism passes through the body isn't sealed or screened....there's an open gap. That's why they weren't USCG certified.

We just ordered a DUI Marine unit this morning for another friend, another odd Ski Boat, a Ski Ray, the Ski Ray has really nice lines, looks similar to the 90's Nautique but is wider taller and has about twice the storage space. The ski wake suffers from this extra size but they are a nice boat, I will look the DUI over on install.

Must be a Mercruiser 5.7 in the Ski Ray. Sounds like a Sportster model, they were about Sport Nautique size and an open bow or closed bow
Unless he has a Spitfire, but they're kinda not too roomy and closed bow. Good looking boats Click on link for some Water Ski Mag info, pages 123 thru 127  link
You won't see any huge differences in the DUI, just the brass screened vents and a goofy plug to fill the space where the vacuum advance went through the housing. and the vacuum advance mechanism disabled/locked in position |

My buddies Sea Ray is the Ski Ray Sportster, the larger of their boats, I was surprised to read it is rated for tournament duty. At nearly 3,000 pounds it does have a larger wake but like I mentioned, it is a nice boat with clean lines and drives good. Long Line wake is large but shortline is not bad. His does have the Mercruiser 350 ski rated at 260 HP.

I was just about to post that I have one from out of my ‘85 with around 400 hrs on it would need polished and lifters.
I also have a stock GT-40 cam with about the same amount of hours would need polished but has the lifters.

Well here it is........... Bucky sent me a picture of the camshaft that came in his project engine
It was a Reverse Rotation camshaft and somebody did their best to stuff a distributor for a normal rotation engine in that hole. "I just ain't seen nuthin like that before" were the first words that came to mind. Probably stuck it in as far as it would go and pushed a little harder and bumped the engine over at the same time. Probably repeated that move a handful of times too.  |

Y'all get all wound-up over a little scratch or 2? That'll buff out.

I was worried all tha missing metal is in the oil galleries but I guess if it never started and ran the oil galleries may still be clean but I would at least run a magnet through the oil pan. That is a First. Someone was very determined to make it work.
