Title: exhaust system design
Post by: williamhawk on April 29, 2017, 01:14:53 PM
exhaust system design for beta 50 hp


would greatly appreciate your thoughts.
first my old system see attached (pic 02,52,33)-had 60 hp perkins #4203 repowering with Beta 50hp.
next plan A system (see attached drawing) with two waterlocks drawing.
even with the two waterlocks, I don't think they can handle the volume of water in the 2"x9'6 hose. (This is my only waterlock option with my limited space available) my old system makes sense to me as there is no way water can travel from the port side to the STB side muffler. but is a 90 degree bend and aprox 3' rise too much back pressure?

please help.

Thanks.

I didn't find the right solution from the internet.
