75 Spectra V-Drive

[78Southwind]

I just bought a 75 Spectra 20' V-Drive a month ago from Greg Fuller's (RIP) father. I didn't know Greg on a personal level but I knew him as one of my river buds (someone I always made sure to say Hi to if I saw him at the river). I had only ridden in his boat a couple times once when I saw him at one of our AVI trips and another when he came to one of my Park Moabi trips that I use to throw a couple times a year. He had invited Lisa and I to join him at Parker a couple times but we never made it down with him to his stomping ground. One thing I will always remember about Greg is his smile, that guy always had a smile on his face.







I didn't really know much about the boat the first time I went for a ride the boat it had an Olds but I knew that Greg bought Danny Donahue's (RIP) old engine and that he had re-rigged the spectra in 2007/2008. I also knew that Greg had done some work to the bottom.



When I got the boat home I measured the following: The strut angle is 7.8* with a 6" drop. The distance between the transom and strut is 25". The cavitation plates are 9.5" from the transom and end 7.25" from gunnels. The distance between the engine and transom is 20". The centerline of the gearbox is 100" from the transom, 4" from the bulk head and about 15" from the deck/dash.







I also did a little research via the boards and thru his close river friends Jeremie and Tom.

Jim Lange (High Tech Marine) re-rigged the boat and rebuilt the engine around 2008.

I sent Jim a PM and this is the information he gave me. The strut was replaced with a fabricated steel drop thru and strut braces, new rails and mounts, relocated V-drive replacing the original Champion V drive with a rebuilt Casale split case, new A22 prop shaft, new Menkens prop, installed new "adjustable" cav plates (originally had NO plates). I never drove it, but from what I've been told, it handles well. The transmission was built by a guy that used to work for Art Carr. I believe it has a Crower crank, Manley rods and JE pistons. All new Manley Severe Duty valves, new oil pump, rings and bearings.

Steve Brule (Westech Performance) dynoed the engine in 2002 and 2004

I don't think Greg ever dynoed the engine after Jim rebuilt it but the engine was originally owned by Danny Donahue (RIP) and he dynoed the engine at Westech Performance in 2004. I sent Steve Brule an e-mail and he confirmed that the engine made in the high 900 HP range with 6.5lbs of boost.

Gary Williams (Williams Carburetors) built the carbs in 2002

I called Gary and he said the carburetors flowed over 1200.

Bryan Lewandowski (Valley Propeller Service Ventura)

I sent Bryan an e-mail and they still have one of Greg's old props and they are in the process of researching his file.

I also found some of Greg's old posts...

...Mines a 75, heavy lay up ( bottom is 1 3/8" thick) 4 full stringers. blown 572. I re-rigged it, moved the prop 10" forward, reduced the angle by 3 degrees to alleviate the stern lift problem.

...Whoever builds Hi Tech Marines trannys is the bomb.

...Blown 572 I will trust Danny on the HP, Replaced the champion with a 12 degree casale moved forward right up to the bulkhead with 37, reduced propshaft angle, new custom steel strut, blastplate at the stock strut location prop forward about 10" My prop is not correct but its running about mid 90s and get there in a hurry.

...Gps'ed it today... 50 @ 3000, 65 @ 4k... 85 @ 5k. the prop I'm running doesn't carry the bow worth a shit and I didn't want Wheeler to soil my seat so that was it...The way I see it if I can ever get my Menkins prop duplicated I should hit at least 107 at 6k : )

...I rode in Lynch's boat at 113, felt faster than mine, but I wasn't driving... my pile has around 1000 hp, 37's in the box, 11.75 X 16.5 Menkins 3 blade. I can hit 5400 with a little more than half throttle, I've stood on it from there a few times but not about to look at the tach?

...I have a new Menkins 2 blade that was originally a 11 3/4" X 17. I ran it once and it vibrated my boat. I just got it back from Valley Prop service after having it cut down to 11 1/2 X 16 1/2". You are welcome to give it a try. I also have a Kindsvater 3 blade 11 1/2" X 16 1/2" with only last season on it, does not work well on my boat it gets squirrely above 80, I have Brian At VPS working on that one now to try and match a 3 blade Menkins that works perfectly but is about done hour wise. I had no luck getting in touch with Dallas @ Menkins last year that is why I bought the Kindsvater. I would bet you would be happy with the 3 blade Menkins, I am going to try to Get Dallas to duplicate the one I have.
