Great! I think I feel like one of those cops after talking a guy off the edge of the bridge/roof.
Twins versus Big single screw for 23 is a classic CSC topic. My feeling is that if you are going with new power, single is the way to go. If you are doing used engines, then twins are a good option. For top speed, nothing seems to beat carb'd twin mercs. Which 150's are you looking at? 150 HDPIs would be good, not sure about the 4s. I think someone with twin DF140s posted that they would still take twin DF-140s over a single DF250, but a DF300 over twins if they could do it over again now. MPGs are better with the big single. Not quite 2x but close, from the numbers I have seen, the bigger the single, the better the MPGs. Not sure what makes more sense for offshore. One argument is that you always want the second engine in case... another is that since 4S are so reliable, generally issues tend to be in the fuel line, or with the fuel itself, which would shut down both twins. Thus you want a kicker with it's own fuel supply. With twins, twice as much chance that something could go wrong, but more likely to make it back in...? ******* METAN does an absolutely awesome job, very very high quality. My impression is that their builds end up coming out nicer than most new boats, fit and finish-wise. They are pricey though, from what I hear. Not because they charge extra, just that redoing a boat the way they do takes a lot of man-hours. One real value of this site is that so many folks have decided to do some or all of the rebuilds themselves, with over-the-counter powertools and some elbow grease. Some folks do the heavy sanding/glassing themselves, and then have the skilled folks come in to install motors, shoot paint, and wiring things up. Another option is Hermco. He is all over this site, and makes the best floatation bracket around. |
