Default 29 Sea Vee Repower

Looking to repower our late 90's 29 Sea Vee. Does anyone have any experience with the twin 150 Mercury 4-strokes on this hull?

Thank you.

I’ve seen a YF in Islamorada with Merc 150’s. No info though.

What does the boat weigh? Twin 150's seem very underpowered to me unless it is a very light boat.

I had a 1993 with full upper station and Yamaha 250 hpdi's. Top speed was 64 light. Typically cruised around 42-44mph with a medium load.

Had an experience where I trusted a friend to fill the oil tanks. Before we left he confirmed he filled both tanks. What he didn't say was that he only used 1 gallon split between the two tanks. On the way back in from the gulf the port motor cut out. We ended up having to run in on one engine. I can't remember what speed we managed to cruise the final 20 miles back in, but I remember clearly how it struggled to get on plane

I am sure it would have done much better if it was propped for a single 250. But I would definitely be hesitant to power it with only twin 150's. The boat was designed for 200's.and I personally wouldn't go less.

Coores and his Keys Posse did a 27 Conch re power with them a few years ago. Do a search for it asit is used as a charter boat out of Key West

Thanks for all of the replies.

TarponOneCharter - Not sure of the boats weight. Hard to find any specifics on the older ones. I agree, the 150's do seem a bit underpowered but as passingas stated, you do see a lot of older 27 Conchs with 150's on them.

KrazyKona - Thanks for sharing you experience which leads me to believe that the twin 150's may be a bit light.

Not looking for a speed demon, just a nice fuel efficient setup. However, i don't want to put a lot of strain on the engines either.

flatscritter I appreciate your response. I just re powered a 28' Pursuit with twin Yamaha 4.2 liter F250's. My boat is heavy, +/- 9,000 lbs. but the F250's are just about perfect for my 28. That's why I asked the weight of your 29 SeeVee. You might find that twin 200's are inadequate.

The 200 Suzukis seem to be a very good match for that hull. I've also seen them with the 175 Zukes.
There are several 28 Whitewaters and 27 Conchs in Key West with the Merc 150s. By all accounts they are powerful and reliable, although as was mentioned, no speed demon.
I suspect the new Merc 225 4S would be an excellent match for that hull.

I would go with the V6s personally, but it will run fine with 150s. When I was at Sundance, we repowered both a 26 Sea Vee and a 28 Whitewater with the 150s. The 26 was a 51 mph boat and 2.5-2.8 at cruise depending on speed. The Whitewater ran 47 and did 2.2-2.5 depending on speed. We’re in the process of repowering an ‘03 29 with V8 250s now, should be fun!

There is a late 90's model with 2018 Suzuki 200's for sale on here. You can probably get some good information from him. He get's 52 mph wot and really good cruise numbers as well. I personally think the 150's would be a little light for that hull, especially if you don't want to strain the engines. If you start to load the boat up with crew, gear, ice etc, the 150's might not be what you really want. Better to have more than not enough.

Seems like a perfect candidate for the new mercs 175-225s. Also I think the boat would hold a greater resale value if you ever plan on selling and move a lot quicker (pun intended) if you had the bigger motors.

they'll run fine on that hull. But, like I tell everyone when asked about repowering any boat, "you never hear people who wish they had gone with less power".

Kwipp - Agree, cannot go wrong with more hp. No doubt would help the re-sale value. Those engines are just very hard to come by it seems like.

Coores14 - Thanks for reaching out. How did your Conch run with the 150's?

I have a 99 280 cuddy with 2013 200 Ho evinrudes.

1.7 mpg at 4400-4600 rpm 40 mph. 1.3 mpg top end at 50 with rebels. 60 mph with vipers props. Rebels better all around and ocean prop.

PM me and we can discuss. Light weight motors boat sits in the water perfect. Lots of torque and a blast to run!

150 or 200 not enough. 250 etc would be better for the extra 8 pounds.

40’s plenty fast at 1.7 for New England waters.

150 Merc 4-strokes will be adequate, but I don't think you'll be happy overall coming from 225 Optis.

Have you looked into the new 225 FourStroke 3.4L V6s?
