Just read another comment, I played with my tabs one day and found that if you put them down the speed increases, not sure why maybe it picks the ass of the boat more out of the water, give that a try see what happens,

How did the mirage plus perform?
How does the boat react when you trim the drive up? Does the hull loosen up as you trim up? Are you trimming up to where you start loosing speed and then dropping the trim a tad?
Please excuse the questions but I have no idea of your experience or skill.

Dont know in your case , but I have a customer with a old 28 Nordic V hull with a 502 Mag that never had a blow out issue till he had a nose cone installed , maybe some hulls dont like them.... GOOD LUCK !

I know this answer won't help much, but I kind of have the same issue. I have a 29 scarab with a stock 502 at the moment, engine is out and getting attended too. I am running a 22p four blade at 5100rpm and can only get 62mph, tried a 25p 3blade and the boat hated it, lost rpm and massive blowout on turns. A friend has the same boat with a 25p 3blade and he can run 65-67mph, just not sure if it is the hull design on these boats but seems you need big power to get over 70mph. just wanted to throw my 2 cents at it, I am by no means an expert. good luck and happy boating.

Drive shower pick ups can cause lots ofslip and lower mph. I've had this happen.
Just mentioning this cause some things like this get overlooked and much time and $$$ get's spent on other things to no avail.

68 mph is accurate on the twin SBC's. Your boat is down 100hp but is also a lot lighter. You should be mid to high 60's but I doubt 70+.
Try what SB mentioned with the drive shower. Weigh your boat. Wellcraft 29's are known to get wet transoms.
