Tom, I am considering to do the same on my deck with Hy-Tech ceramic beads, did you use them? Singleprop
If the recommendations from Marinelightning.com is to be followed some metal strips should be welded onto the hull side (under water). What...
I used John Deere Document AG-24 to calculate the length. I think it is quite conservative (no extra padding needed) and I came up with a total of...
Fast Fred, Just the reply that I was looking for. On the other thread I asked about installing a heat exchanger cooled engine in...
Hi Fast Fred. there is another thread discussing this issue now and I raised the question about over cooling the return water as well. The...
