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?
You've got a couple issues that the Beta guy may not be aware of. First, it's an old IOR design of some sort, and you can cruise for days with the stern squatted down to the waterline. I have fond memories of sailing for three days with my entire engine control panel a foot under water in the cockpit (Catalina 38). So figure the actual waterline as the sheer at the stern. Secondly, even with the highrise elbow, the engine can flood. I think you need to get some professional help from someone who knows your boat very well. (What kind is it BTW, a Lapworth?) I'm with Gonzo - reproduce the old arrangement. Did the Beta guy say why he wouldn't stick with the original?
This is a German Frers design, and on top of it built by Frers & Cibils. I would trust the original design and construction. If the Beta guy thinks he can do better, he should provide you with a design he will guarantee to work.
I posted on the Beta forum and got this answer from Stanley who knows his stuff from what I can tell; and I posted a question, see below
from Stanley;I think that your standpipe arrangement as used on the old engine should work just fine.
I would definitely build a new one and also include a new flex section between the engine and the standpipe.
It won't hurt to fit an anti siphon valve in the water line between the heat exchanger and the water injection point of the standpipe as well. This will also be mounted above the waterline.
I hope that this helps, Stanley
Thank you so much for your advice.
I have drawn in an anti siphon loop as you suggested.
but I have a mystery, its been 10 yrs since I pulled the motor and I don't remember what the 1/2" fitting on the upper fitting of the water jacket went to, any thoughts
