God Bless You!
The rule of thumb from the CAT Application Guide book is not engine specific, works great on Detroit's, Cummins, MAN, MTU's, etc. Great for...
No. Quoted from the Caterpillar Marine Application Guide: [ATTACH] They are giving a rule of thumb of 450 rpm/2" pitch = 225 rpms per 1" of...
The first number is propeller diameter the second number is pitch. If you think you have a throttle linkage issue , get that fixed first. A rule...
Glad it worked out for you, like to hear success stories :)
Sounds like you are good to go, glad it all worked out for you!
Looks like a great choice to me ;)
I have not seen the machinery space layout or been on this vessel myself, but boats like these typically have a one piece transverse aluminum fuel...
Those are nice rudders, quite an improvement of flat plate designed rudders.
NTSB just released preliminary report, Crew members were asleep, no one on watch:...
Great information. Keep in mind that Donzi 54 mentioned he replaced his struts during his repower (I recall), so you may not have the same amount...
That is certainly the key issue under review. Rethinking all my charging cords for battery devices in the household, no more overnight charging...
I think Viking is predominantly Veem Interceptors, they have a great following for SF over 30 knots. The advantage is that you can account for...
So I see a few things: That strut looks nice and massive, the barrel looks plenty long enough to take a longer cutlass bearing, hoping you can get...
While you are currently in discussion with ZF, I would take it one step further and ask them what would be the optimum gear ratio for your...
The best case is to use the existing strut with a larger cutlass bearing. I believe the Donzi 54 repower went up in hp significantly so the strut...
More food for thought. Keep in mind that there is a relationship between shaft diameter and other key geometry items in the propulsion system. A...
Nice work on the ground level :)
All the above numbers are based on AQ 22 HS (High Strength), not the lesser strength normal AQ 22. AQ 22 HS has a yield strength in torsion of...
Here is the shaft calculation from the Western Branch Metals catalog: http://www.wbmetals.com/ [ATTACH] As far as the Safety Factor goes, ABYC...
