Hi Doug Thanks for your information. This is only an idea because the first Donzi 16 came in I/O , O/B and a very rare V-Drive Inboard by special order. Iff a Donzi 16 have the space for this setup, I believe a Bertram 20 maybe could. David Vila

Buzzk What you think about vee-drive configuration. David

EFI That be great for fuel economy more Torque and HP,I preffer carbs, they resist more corrosion less trouble and I can have one spare, changing very easy. If make the repower I let you know the numbers. Rochin

David My boat at this time is in total gelcoat and outside refinish proces. The Whaler is in my house. I believe the boat will be ready late this month or first week of August. I can send you the pictures of the Whaler with Davits and later in the platform when finish the boat. David Vila

I have a 33FBC and a 9'Whaler tender. I buy a Weaver Snap Davits for platform mount. Also buy a FULTON PERFORMANCE Swiveling Dinghy Engine Mount Bracket. That bracket let you mantain the engine in upwright position even the tender is 90 degre to any side. I use a 4 stoke Yamaha but the base can hold...

MORE PITCH IS BETTER THAN CUP AND 4 BLADE IS BETTER THAN 3. THATS MY PERSONAL EXPERIENCE IN MY BOAT. I COULD BE WRONG BECAUSE READ DIFFERENT OPINION IN THE FORUM AND NOT MATCH WITH ME. I START A RESEARCH AND FIND THIS. FOR CUP.PAGE 3 http://abcprops.com/proppdf/PropellerCup.pdf#search='PROPELLER CUP...

Frank I use longer tabs and work well at low RPM 2600 and at hight RPM 3400 I can adjust them. I tell you about the tabs because I believe it can help you and not for miss the point of efficient cruise RPM for the 454s Sorry for that. In HP BOOKS BB CHEVY MARINE PERFORMANCE By Dennis Moore,compare t...

Frank,I find this accidentally. In my last trip to Virgin Islands my starboard engine dont pass 3000 rpm. If I try the engine drop the rpm and almost stop, have to back the throtlle for stay running. I remove the flame arrestor after the trip and see the upper flapers of the secondaries barrels (fue...

sla168 Thanks for answering my question but I made a mistake. I change the forum an think you have a FBC. The reason I ask the dimensions is because I install a Compact 2800 rpm Next Generation 5.5kw Diesel over the strainers on my FBC. With this change I eliminate some weigth specially in the aft. ...

Hello David If you have a Rochester Quadrajet the best fuel efficient cruise rpm is the top rpm you can reach with the secondary barrels disconected. The primaries triple ventury barrels of this things are by far the most fuel efficient of all carbs. You can also see vissualy when the secondaries op...

Do you buy the gen already? If yes what are the measures. David Vila

Work better, In my case cruise at the lower plane speed in the Atlantic Ocean with an average of 4 to 6 foot waves. Thats four blade give to me. I install longer tabs have a new 5.5kw D compact gen over the strainers in the front of the engines .Later a new 4 blade props. I can plane my boat 200rpm ...

Hi Doug Do you test the compression of the engines. What you use to measure the speed. David

Yes Doug David Puerto Rico La Isla del Encanto [8D]

I think the engines will fit but I agree in the gears issue. I just try to repower my boat without complicated changes because my gas engines work well, I only want to change to diesels for safe reasons. If I buy the Cats 320HP , can use 1 1/2 shaft changing S-Box and the bushings of the struts, usi...
