Re: Wellcraft Nova 250 Rebuild - Pre alpha/alpha max HP
Hey iboats - totally forgot about updating after things got rolling down hill. After 18 months and more $$$ that I'd like to own up to, she finally hit the water this past month. The engines sound great, the 4bbl carb upgrade coupled with the high performance heads make a world of difference on the top end. All in all, I gained around 15 mph on my top end, went from 188 hp/engine to 275hp/engine, and noticed an increase in fuel econ (ever so slight, and most likely due to the 4bbl swap). I ended up having to swap out the outdrives, one was shot and had water in the oil after taking it off the transom last year. I went with SEI alpha 1 equivalent, and did a counter-rotating port drive upgrade. I wont claim wild improvements in straight line tracking, but I do notice it is much more maneuverable around the docks. I ran 4" exhaust out the side (previously had 3" and some wicked bends I wanted to eliminate), and will say that I'll never work with 4" in that type of set up again. That was hands down one of the biggest challenges to get set up. I am glad I kept it side exit, as it gives the Nova a unique look and sound that no other boats her size have. Turns heads everywhere I go, and cant wait for next season. I'll post more pictures once I get them off the camera - thanks all for the advise throughout the months. Feel free to comment or ask questions -
