New Scorpion DD, WaterThunder powered boat

Post by Waterthunder »

This aint my boat it's a buddy's. Were gonna have a lot of fun with this project. Short block being assembled next week! So now we have a flat bottom production standard hull with stainless rigging. Besides a few people on here claim Scorpions don't run good so she should be a real terd with a 300HP DD.

Waterthunder, did you finish developing your secret thrust bearing,
and will this boat be equipped with it?
Nice looking boat!

It's getting a Sensenich Saber with a new type of hub we are developing together with Sensenich. The new thrust bearing will be on my DD which is going together now. I'm keeping our new prop hub design and thrust bearing out of site until everything is done. I'm sure the prop hub design will be copied ASAP once everyone see's it.

A good bit less then a O540. A LS with a gearbox is lighter then a wide deck O540 angle valve. Now with a DD you are even lighter because you took of the gearbox that weighs 80 to 90LB's.

are you adding the weight of the radiator and coolant to that and if so how much lighter overall is it than the 540

Yes I have been weighing every engine both car motor and A/C I have had in the shop over the past ten years with a calibrated load cell scale. All weights are complete the car motors have radiators and the A/C's have oil coolers.

Thats awsome . I have always loved the DD carmotor , call me crazy but I do, they are very reliable, smooth, and set up rite do awsome runnin dry I know mine did. Dave you prolly dont remember me but about 4 yrs ago you and another fella were on your boat out with a laptop tuning the engine and we all got rained in at the oakhead for a couple of hours one afternoon you gave me some good advise and it did the trick. I had ablack and yellow 13' lazer dd350. But anyways keep on keepin on we love what ur doin. :thumbleft:

I think this is a pretty cool project. Open some peoples eyes to what actually can be accomplished by the average guy for a LOT less money then what some of these new rigs are costing.

Waterthunder, if possible, could you give us estimated overall cost once the project is complete?

Neil wanted to file fit his own rings so we stuck him in the corner of the shop and let him file away. Partly because I hate file fitting these type of rings. To give him credit he did a great job and held all gap's within a .001 tolerance. Neil weighs over 320 just like I do so all you A/C guy's should clobber him with your O540'S.
