If the outer drives are on extension boxes and raised then it might not be an issue. The drive height is an issue same as ALL boats. You have to experiment with it and see. Not too many 419's repowered due to not being a fast boat to begin with. The remove 3 and install #6's. Sounds great. Except the structures, transom, stringers, bulkheads, mounts, toilet, generator, sub floor, everything would have to be gutted and new installed. I would say the idea of totally redesigning the back 1/2 of the boat is not the type of information the guy is looking for. What do you have for power in yours? |

Problem is the 3rd drive trashing the center prop efficiency. If it was just the 2 then the issue of spacing is not as much of a problem. BUT..... How about the outboards with 3 and 4 motors running beside each other??? Do they have issues? IDK......Something the quad outboard drivers might be able to give some input about |
I can not give much information on my set-up because I just finished a power upgrade myself.
Went from stock 502EFI Mercruiser 250-300 hours on tach to trip 540CID 650HP ea. on the dyno. on 87 pump gas. Lightning tubular exhaust. Replaced 93 Bravo 1 drives with 2001 BravoXR drives on 2 of the 3. Looking for drive parts to make all 3 XRs and wanting a DWP lower for the center drive. Thinking the DWP center drive will assist with the long distance the bravo sea water pump has to draw. So mine is a "project in work" Replaced genset and a few other items cleaned up when all 3 motors were out. Tried to get the mess cleaned up before it got too cold and just did not get it done in time to make it worth risking winterization issues. |

remove all 3,install #6 drives and the other 2 engines in a staggard form..sell all the bravo stuff..will save a ton of money when all the bravo stuff starts to brake after 10hr's of use with the 800 hp engines.

Waconda,
When did you run at Grand? There was a BT running out of my marina for a while - thought it may have been you. OPIE272 and I both run 419's - he's going to outrun me though! |
