It sounds like this is a normal Classic hull with a blackhawk drive. As stated, they are not intentionally built with a hook, but many of them do have hook.
I think a few people have tried this...
I don't think I do. I sold mine long ago and can't recall if I took any pics. Going off memory there was a slight rocker the last 6' or so of the boat
As stated, the Blackhawk is a different beast. IMO, Donzi put too much rocker in the hull and made the boat flighty in certain conditions. However, if you want a "driver's boat" that is fast and...
No special tools required for a KC that I remember(which surprised me). He did borrow a manual and I will try to find out thevbrand/publisher.
My buddy's KC was doing the same thing. My thoughts were it needed to cool before it would shift into drive again
We pulled the clutch, flipped it and lapped it and no problems since. I...
Or;
500 HP@ 4000 RPM = 656#' T
600 HP@ 4500 RPM = 700#' T
700 HP@ 5000 RPM = 735#' T
That's an increase in the T curve.
Exactly! :thumbsup: In this case the hp increased 200 vs 79 for the...
I know, I know!Because
T = 5252 x HP
rpm
And if the HP goes up significantly in a narrow rpm range, the torque has to go up also.
The formla won't align properly, sorry.
how can the tq curve be that flat, when the hp curve gains over 100hp... no can do
Hah? Why can't you have a flat tq curve with hp rising 100+ hp in 1000 rpm?
MOP external steering is a must with the stern jack IMO. The longer "lever" puts much more stress on the gimbal ring. The advantage is this puts the prop closer to the surface, not deeper, when in...
525s have a slightly different pattern due to the Edelbrock aluminum heads. It's my understanding that the 496 exhaust will bolt up to a 454/502 but the holes have to opened up a bit, as the 496s...

Yikes that is pretty ugly! Depending on the damage done it may be better to start with a fresh Gen VI short block.
f_inscrenname gets it. From what I have seen there is nothing special about "marine" cams, valves, etc. You just have to make sure the overlap and LSA will not allow reversion. Look at a Merc 525...

How about a 20 foot Cig with a V10 Ilmor and a Blackhawk
Damn!!!
I agree with whoever said to have Crockett help/dyno the engine project. He rebuilt a friend's 502 and with a procharger he dynoed at 730hp. He also fine tunes the boat with a A/F gauge and his...
Of course there will be some aeration. But a blender is still a blender. I can make bubbles by farting in water, does that mean my ass is comparable to a scuba tank?
I should have known better...
I agree, lube topics go in circles. 300EVIL said it best, change your oil often.
Of course it wasn't foamy, you have an actual gasoline engine under your hatch, not an electric blender!
Lots of guys run Rotella in marine applications. As stated it has a fairly high Zinc...
Too funny. A friend of mine has over 800 hours on his 454 in his boat using nothing but Castrol GTX from day one.
Most Rotella oil has a 1200ppm zinc count. Whether that is "high" or "low" is subjective. It will be higher that passenger car oils and lower than racing oils.
Ding ding ding!
I love oil threads as everyone has an "opinion", key word being opinion. Change your oil and filter often and use a good filter.
I really like the guys that say, I won't used...
Yeller, how bad is your 496? What about rebuilding it with forged internals and using a MEFI system? A friend toasted his 454 Mag a with a Procharger two years ago and he had Tyler Crockett build...
Volvo also had a 600hp 540ci EFI motor also, it was actually built by Innovation Marine. Tough to find but a couple years ago there was a brand new one for sale.
