Ouch, that's a heavy engine! My Steyr comes in at about 300ish Kg ( about 660 lb ).
The Aussie boats use Steyr and yanmar.

That's a question for the US Navy on why they chose the Cummins/Konrad setup. From what I have read, somewhere ~1999-2000, the US Navy switched the ribs from Volvo/Duoprop to Cummins/Konrad. The Volvos just couldn't take the load. So, I'm guessing the Cummins/Konrad was a durability choice. Also, they chose durability over performance. The 5.9L block comes in variations from 140-370hp depending on turbo/aftercooler/fuel pump tuning. The 180hp is turbo charged and "continuous duty" meaning that they can run at WOT for 6 hrs at a time.

Yes, a 315 hp Yanmar would be nice... And it's 200 lbs less than my engine!

+1

I gave my trailer fabricator a hard time - there is a wheel on the tongue jack of my trailer. I couldn't move the thing by hand if I tried!

I think that we're getting off topic here but since I started the thread and am adding to it, I think we're ok!

Right. What I'm saying is that as long as the water is not aerated, it shouldn't be a problem. Speed doesn't matter (I think), not does water moving at different speeds.

Now you have me thinking...use wood screws to put the transducer on a 2x4 or something a bit thinner, stuff it down between the swim step and the transom so it doesn't move and try it out.
Thought I said that.

Anytime! Season opener this weekend and I'm stuck in LA because my girlfriend bought tickets to some concert for Saturday night...not too excited by it.
Later in the season at the very earliest. Just bought my Mom's house from my siblings; gotta see if I can actually afford it now.

Don't have that problem! The Cummins alone is 1100 lbs!!!
Problem is when the trailer is unloaded. The wheels hold a bunch of air, and if the trailer is light enough, they'll float the back end.

I don't know yet...it seems that I'd get the best picture that way out of the device. And, there are plenty of threads on tht that say you can remove 5200 with some heat, chemicals, and a putty knife.

Very tempted....

Won't happen this weekend. Catalina bound...I'll have to live with just the P79.
