Trojan Boat Forum

Well I did a search and found someone that had changed an 1978 f26 to an outboard. Questions I have for you pros here The fella that did it states it goes 38 mph with the outboard. You can see from the video he appears to jump on plane pretty quick. This being said what in your opinion would be the least hp outboard to get this boat onto plane? I'm sure the thought of 250hp=38mph 125hp=19mph has a hiccup I'm not seeing.
second question if I can get the pic up. The owner removed pretty much all of the back stern wall. I'm only assuming it was merely to allow easy in and out of water / dock ect. I think and haven't verified yet that the pod is somewhere around a 36"setback. alright let me know what the math works up here , curious to get some input.

No transom?!?!? No, thank you!!

It looks like the stern was reinforced quite a bit. I don't see why you couldn't have a transom. The engine is back far enough that a transom wouldn't interfere with the turning of the outboard.

Really depends on what they did to what's left of the transom. Unless there is a removable drop in door, I see a falling overboard hazard while underway though. Nothing there to prevent it. Also doesn't look like the rest of the hole is covered where the control cables enter the hull. Looks like they're having a good time though.

I'm leaning more towards leaving the stern wall as is. So anyone have any ideas/guesses as to what hp would be required to get it onto plane?
there must be a formula for it just don't have a clue here.

Interesting configuration!! If this is a 1978, it is not an F-26, but a F-25 EC. 9 foot beam and 4800lb dry weight.

I would not put anything less than a 175hp ob on, as you need need the torque for hole shot.

Looks pretty dumb to me - what is to prevent people from falling over?? I wouldn't have complained if I saw some stainless steel bars or something!

This boat would sink in Lake Michigan.

Still has to be reinforced. They are not designed to handle that kind of weight hanging off them or deal with the stresses involved while underway. Nor are they designed to take the load needed to push the boat forward. You'll start seeing cracks at the corners soon after a few good runs, a few decent swells will make it happen much sooner. If you're going to do it, do it right, overkill if you have to.....can't be too safe.

thanks for the input. what the plans are is to beef up the inside back of stern and neighbor that runs a machine shop said we can hook onto the main stringers behind the fuel tank and angle them upwards to connect to the stern reinforcement. yes overkill I understand very well. So now it looks like I'll be parting out all original engine stuff. will have the wet exhaust,sleeves and elbows as well as the prop shaft ,prop ,and prop strut, steering lines, hydraulic steering piston? ,gas tank, transmission, throttle/fuel controls ect ect ect . am going to sell it all off to help purchase the "pod" I need to order. anyone looking for spare parts lemme know whats a fare price and we'll get it out come spring " our spring isn't coming for another month I figure"

"Yamaha LF250XCA Outboard Motor MSRP: $25, 530.00" tons of work needed to reinforce the transom on a inboard powered boat to strengthen it enough to accept an outboard. its alot to invest when you could probably purchase a newer outboard powered boat for less.
Just my 2 cents!

heavens no I wouldn't be spending that kind of money. I have a brother that owns an outboard sales/repair business here. Plans are to purchase one from him either at cost or buy a used one that he deems in good working condition. I can get a 2005 130hp Yamaha for about 3k but want to make sure that engine would get it onto plane. Point here with this setup is our marina "directly" across the street has a shallow channel in and out . then coupled with any problems with an outboard I have a close relative "brother" that will help with any issues , unlike an inboard problem that will automatically costs me what $60 per hour labor min. and I would have to get the broke boat to the other marina if it were inboard. Don't really care about speed as much as a reliable powerplant.

Someone did it to one of our "stepbrothers"!

If my engines go I am going to slap on a couple of battery operated trolling motors to my swim platform. I fear it will never get on plain however. transom is a must. A following sea and "woosh"
