Hello,
I'm starting this thread because I have scoured the internet before I decided to do my conversion and very few threads ever showed the completed project.
The reason I'm doing this project is because the pilot house is perfect for fishing here in the northwest in the cold winter months but the I/O was always a PITA to winterize in preparation for the next fishing trip. (boat lives on Trailer)
My boat is a 2004 Trophy 2359 WA.
I had a 260hp 5.0 mpi w/ Bravo 3 in it and 22p props. I am converting to a Honda 250hp with a 30" shaft and a SS prop. (not sure on pitch yet as they have never had a boat like mine in for the conversion).
The bracket was built and installed by Dwayne of PDR marine in Bellingham WA. He has built and installed several of these brackets and if you look at most outboard Sea Sport boats his bracket will be on the back.
[FONT=arial, sans-serif]As for the transom: he was quite surprised on how well they built the boat. He didn't need any extra gussets or bracing for installing the bracket and did a magnificent job of glassing in the I/O hole along with all the other holes for the kicker and swim step. I also asked him to add a couple transducer brackets so I don't have to drill into the actual transom when installing the transducer. He said of cheesy plastic he'd make them better. (I think they look factory glassed in and gel coated) The bracket I chose was a full swim platform with kicker bracket and is standard for the positive flotation in the center. [/FONT]
It's currently in Oak Harbor WA getting the motor and all new digital instrumentation installed and should be completely finished in 2-4 weeks depending on parts availability. The dealer I had picked for the motor is very excited to do this as they have not had any Trophy boats getting the conversion. (I have not mentioned their name because I have not asked them if it's ok yet.)
I'm hoping I took enough data on the old motor to show any differences in the 2 but will be unable to GPH because I didn't have that on the boat and never tried figuring it out long hand.
The I/O would comfortably cruise at 30knt at 4k revs all day long. So if I get the 10% increase in cruising speed I should be able to get 33knts at 4k revs and still use less GPH. (we shall see)
As for the handling the boat with the Bravo 3 handled well and I'm hoping since the fuel tank and most of the cockpit being at or in front of center line of the boat I'm thinking it should make the Honda operate smoothly and hanging the motor farther back might actually help balance the COG better.
I really love my trophy and I wish they would have made the pilot house in an outboard to begin with but they didn't. So to find a boat even close in fiberglass and an outboard runs way more then what I paid for the boat and the new conversion / Outboard
I'll make sure to post up more pics as the boat is finished and has been run a bit to get more data on it even if it doesn't work out the way I hope. Please ask any questions I haven't answered in my long winded post and I'll really try and get pics and data up as fast as I get it.
Thanks, Joe
