Default Repower 2001 Contender 25 Open with Yamaha F250s

Looking for input on repowering my Contender 25 open with Yamaha F250s. Previously had 200 HPDIs and loved the way they worked on that hull. After much research (thank you contributors on previous threads on this topic) I've settled the 4 cylinder 200 vs larger/heavier V-6 motor debate (at least in my own mind) and settled on the F250s. What I am after now are suggestions on props and mounting height from anyone who has this configuration to save some time in dialing it in. Saw some threads that discussed this topic a few years back and would love to hear from those that went this route and what their thoughts are after living with it a few years. Thanks everyone!

Twin 200's, 950lbs (approx)
Twin F250's, 1102lbs (approx)

You're adding approx. 150lbs to your 2001 transom. Just curious if you talked to Contender? Boat was built before 4-Strokes arrived. **I'm not saying the boat-transom can't handle it, just curious what they would say?
*I've seen a 1997 Contender 27 (30' loa) with twin F250's and it has stern squat with the added weight, guy ran it a year or so put many hours on it, then had a fuel tank start to leak..I rode in it when he had the 250-2strokes, was fast and no squat, guzzled gas though...

A good starting point would be to mount at the same hole as your 200's. You may want to inquire with PropGods regarding Props, they helped me a lot. Good luck!

So which are you settled on?

That hull runs perfectly with 2 x 200, no need to reinvent the wheel.

F250 3.3L = please don’t (the ride changes completely)
F250 4.2L = yes, they run ok with a pair of Bravo or Rev4 props (will be a fast boat).

Homey,

Yes emailed Contender, waiting on a reply. Saw a thread where Contender was OK with a 525 lb motor but not a 600lb older 4 stroke. Not sure what the cutoff is in their mind but I have convinced myself convinced the 550lb 4.2L will be ok. I did a very scientific test on the weight change impact while just floating. I sat my fat butt on the motors and measured how much the boat "sank"... 3/4 of an inch. I also know running the boat with 1500 lb of full bait well, dive gear, coolers, and fat guys in the back does change the ride but not negatively to the point I ever worried about it. The added outward torque on the transom from the extra horse power is probably more of a concern but I think the hull is rated for 500hp.

Agree on the starting point for the height, just wondered if someone had already "dialed in" the same motors. Thanks for the info on PropGods will definitely reach out.

Blew one of the engines so have to do something. Settled on the new 4.2L F250 (550lbs). WIsh they still sold the HPDIs, I am a big fan. The new Mercury's 225s (475lb) are intriguing but there is up to year wait to get one they tell me. I have a keys trip planned in July and a boat with one motor. Options are limited.

I know this doesn't answer the question but I just repowered a 28' Pursuit CC with twin FBW F250's and I love them. My prior motors were 3.3 mechanical F250's and the FBW, mid range torque and throttle response is spectacular. The only downside for me is my fuel economy at cruise has suffered slightly but as the
motors get broken in I see that gradually improving. My boat weights about 9,000 lbs and I believe you will be considerably lighter. I'm turning Yamaha SSII props in 17 pitch. WOT = 5,900 rpms @ 52 mph.

Thanks. I stuck with the mechanical vs FBW trying to save a few bucks. May regret that later. This was an unexpected repower, although knew it was coming sooner or later. Yes quite a bit lighter, I'm excited to see what she'll do, even though it probably wont change how I drive her most of the time. I had absolutely no complaints with the performance of the HPDIs.

I was also going to go with mechanical F250's but realized that all my rigging, gauges, binnacle, cables, etc. were all nearly 15 years old and should be replaced anyway. After figuring in the replacement of all those items I was equal to the cost of the FBW motors. And for me the FBW were available when nothing else was so that made my decision easy.

I had seen a 25 open for sale in the key with 300 Suzuki’s I believe they are just under 600lbs.
That boat was a rocket.

Thanks, already purchased. Sounds like none stay in stock too long though.

LivingBroke, please keep us posted on the install and results. I have this same boat and plan to repower this winter. Going to shop yamaha, mercury and etec g2 and see which one has the most cons. When is your install date?

I had an 04 25Open with 4.2 F250's. Can't say how the ride was different with the added stern weight. Boat was like a sports car with 500 on the back. Always ran 1/4 tab. Motors were one hole up from rock bottom. 3 blade 21P Yamaha props. Stay on plane at 20mph. 63 at 5800rpm. 40 at 4000rpm. Usually 1.7mpg key on-off on a fully loaded tuna trip.

Hopefully next week. Will be in the Keys for the month of July so she should get plenty of testing! I will keep everyone posted. I just had the fuel tanks replace so I'm pretty close to having a new boat.

Pooldoo73,

Awesome! Exactly the feedback I wanted to hear. DId you try any other motor heights? I think the 21 props are the same ones on my HPDIs so I was going to try those first.

Motors going on... I'll post updates as I get them. Excuse the dirty water line, didn't get a chance to wash her before taking her to the shop.
