That is the gist of my question. I don't know the weight and thrust differences of your possible O/Bs. ....looks like you left yourself good safety factor/wiggle room.
Your design drawings calculated several important factors, CG, forces etc based on a specific O/B package. Do your alternatives above fit within your design?
I recall you previous big boat. IIRC the marina delivered and dropped it on supports in your drive. Trailer is nice. Do you have a drawbar vehicle to get it back into the water?
I made the twofootitus upgrade four years ago. Merc 180 hp 4.3LX to a VP G5 4.3 250 hp.
I compared several brands of 18-20' BRs. In all cases where the boat offered both I/O or O/B, the O/B model at the same power was considerably more expensive. Also the O/B version offered less hp than the...
A bit off the main topic, but I want some education about I/O vs O/B in saltwater. I'm freshwater and realize the maintenance simplicity of O/Bs vs I/Os.
I see many/most O/B boats in saltwater. I assume the engine housings are aluminum, but still subject to corrosion, as are the drive hsgs.
Are...
That extra 44+" of planing hull has been in the back of my mind. I'm thinking a good outcome. Hopefully a lower planing speed and maybe being able to abandon the trim tabs.
I retired working in heavy equipment transmission/drive train manufacture.
Coarse threads in both cast iron and steel were the norm. I mostly set up the tooling and processes, so I didn't much care why. I assumed with the joint fasteners we used and the required torque, coarse threads provided...
With my one project with resin/filler/membrane I used a quart ziploc with a corner cut off to apply the goo.
It was a hot summer day and my first try with a mix kicked shortly after I got it into the baggie. I never got it applied. The bag was so hot I pitched it out of the boat onto the garage...
I just tuned in to this post. ....Nice project.
I haven't gone through all of the threads, so you probably explained this earlier:
This is going to move a lot of weight a long distance aft. What do you expect as far as floating waterline, planing, etc.
