20ft SeaCraft With Twin V4's??? Just Thinking OL..

[red20]

wow what a learning experience. I say no bracket on a 20. Back to the original question abot twins on a 20'. Last year, give or take a year, there was a 1984 20' w/ twin 115 hp mercs in the trader. Seemed to use the standard cut out? If you do it post some pics. [img]/images/graemlins/smile.gif[/img]

Red20, thats seems like a lot of weight for a 20 on a stock transom. Df115's are 385 lbs. and the newer 2 strokes are not that much lighter. I could see possibly doing it with older/lighter 2 strokes, if thats your thing. But in my opinion if you sit 700+lbs. on a stock 20, your gonna sink.

Back to the 45% hull thing. I agree with Fr Frank on that. I have a 15 whaler dauntless, and that boat can't help but porpoise. Though my feeling would be, if you put say a hermco bracket on, which is more or less an extention of the hull it would give greater than 45% there for eliminating the problem. But I'm not going to try it.

Dunk I wouldn't put twins on a 20, my 23 ran so much better with the old V8 Rude than the twin 150's it wasn't even the same boat. My theory is with the VDH the hull will pivot on the the center deadrise and get up, with the twins your trimmming it on the outer deadrise, it really wasn't the same boat and since I had an extra hole I had them stick a 55MPH speedo in, not enough, would go all the way around to the 0 peg. 1978 23 Sceptre V8 Rude, 60 should easy with a big single.
