Re: Marschall DE25

Thank you very much Jacques! This eliminates our fears of being underpowered. The 115HO should increase the range of the boat over a 200HP too with the same fuel supply as well. I would not mind at all having to step over the raised bridge deck if it means making the boat more seaworthy and raising ...

Re: Marschall DE25

Thanks for the replys, guys. It was very informative talking to you this weekend Jacques. We would love to be able to put a 115 E-TEC on it. Looking at the 25" shaft 115 it weighs 405lbs. We aren't looking for speed but instead the power to hold the boat on the back side of a wave in a followin...

Re: Marschall DE25

I think we discussed that and the conclusion was to move the tank. The tank is a variable weight and precise calculations don;t make much sense since it's weight will change. To move it as you propose will compensate most of the time and I see no alternatives. I also remember that we discussed incr...

Re: Marschall DE25

OK, I forgot that you were discussing heavy loads. One of the issues is that once you move up to 150HP they use the same block as the 175 and 200. The weight of the new yamaha 150-200HP in-line 4 cylinder engines is 487lbs. The thought is to move the fuel tanks into the cabin in front of the compan...

Re: Marschall DE25

It was a 115: http://forums.bateau2.com/viewtopic.php?f=2&t=25532&hilit=de25+de+25 Top speed is 30mph+. The boat is designed to cruise between 20 and 25 mph (he shows knots). That is also the best fuel economy. Build light, she'll get at 20 mph with a 50. I think the 115 and the 90's are us...

OK is the largest factor the weight or the power being an issue with 200hp?

Re: Marschall DE25

Very nice pictures and report. Thank you for posting. Yes, I know about the bow shape on that boat. It was a compromise between ease of building (bending the ply) and performance. It takes more work during assembly but it pays in performance. That volume in the bow helps a lot in semi-displacement ...

Re: Marschall DE25

A little bit of a learning curve but after help from Cracker Larry things are going smoothly. http://gallery.bateau2.com/albums/userpics/88988/IMG_0533.jpg We cut the stringers and temporarily nailed them together to keep them in place. http://gallery.bateau2.com/albums/userpics/88988/IMG_0557.jpg W...
