I installed steering controls and did the first sea trial of this 26' Searay with its used df300 Suzuki on a custom fabricated aluminum bracket. The customer brought it to us with the bracket and engine already installed. The boat handled really well with the outboard and reached 37 mph with a much too steep 27 pitch prop that was supplied by the owner. I like to see the 4 strokes reach 6000 rpm. With the 27p it only reached 4500 rpm which is probably well below the engines 300hp output but did surprisingly well considering the low rpm. I expect much better performance with the correct prop. I would imagine 45 + mph would be reasonable probably with a suzuki 16x20 three blade.

Would it be possible to put twin 200s or a Yamaha 425 on this thing? The 8.2 liter Mercruisers put out 430 horsepower.

This looks good! Do you have more videos? I would be interested in such conversion. 25Feet is ideal for family trips too, however not too keen on sterndrives

I have another i will upload of a big old commercial fishing boat we converted. Once a i/o gets close to 10 years old in the saltwater they all turn into disasters.

Had the 5.7 on my 27 crownline felt it was a little underpowered in bad chop

this is sweet! have a 1984 210 fisherman thinking of doing the same with an entire refit. what hp outboard and shaft length do you think? has a Alpha 1 with merc 305.
@darrenalkire5281
@darrenalkire5281 4 года назад
You want to set the bracket for a 25 or 30 '' motor. A old 305 is probably equivalent to a 200hp outboard and maybe less.

Did this setup get tuned in? Did the motor go up a notch or two? What was the final propeller selection? Can you post the final performance results compared to the previous power? Neat modification and nice video production.
@darrenalkire5281
@darrenalkire5281 3 года назад
Yes it is all tuned in now. All aspects of performance are better than the 5.7L mercruiser the boat came with according to the owner. Not sure of the specifics I never ran it with the I/O.

Hi mate I have a Amberjack 270 same year. The old mercruiser is starting to give me a lot of trouble. Who built the bracket? Would you have the plans available?

Did you ever get a response. I have a 2006 270 AJ as well and am interested in this. Could be a great alternative and cost savings in the long run. Its a great boat otherwise.

A 20 pitch might be good, you also have a lot of prop slip. Dirty hull? Maybe try a high-rake 20p 4-bladed prop and trim the engine out a bit.

Hull was clean. 17x16 Suzuki 3 blade was the ticket at 6300 rpm trimed out and light.

The whole project including engine probably cost around 50K.

Looks like a very expensive swap for loss of power. The maintenance will be better but man that’s a lot of work and cash.

If you didnt rebuild the transom it is going to fail eventually. An I/O transom is not designed for the torque of an outboard. This is a tragic mistake many people make.
@darrenalkire5281
@darrenalkire5281 4 года назад
Some boats have a sturdy enough transom many dont, that is why you strengthen , brace, and if needed completely rebuild the transom thicker.
@robertp7209
@robertp7209 4 года назад
The I/O mount is carrying the torque against the prop, particularly because of the offset between motor drive shaft and prop shaft. It’s not an inboard. If the I/O mount bolts were removed, all hell would cut loose back there. The new bracket spreads out the forces over a very large area of the transom, where as an outboard mounts with relatively tiny contact surface with just 4 or 6 bolts, same for I/O mount. The new bracket has about a dozen or more bolts.
