Will it work or will it kill me?

[InterMechanico]

I have a 1987 Hourston 18.5 hard top/bulkhead boat. It is a commercial hull, and It has a volvo aq211a sterndrive (215hp) at present. I would like to pod it, and I have a low hour yamaha F250 outboard. The weight of the outboard is 608 lbs or so. I'm not a reckless operator, but I also try not yo make stupid decisions where they can be avoided. If going new, I would probably first consider a 150hp fourstroke merc.

I have seen a 200hp on that hull (not podded) and it went like a scalded cat. Seemed pretty jittery to me.

It will currently do about 45 mph at WOT with the AQ211A. I could probably have the ecm detuned to 200hp or so, but maybe why bother...
Maybe not such a great idea, but fun to imagine

Way over powered. Had a 275 Verado on my 20 hourston and never saw wot. Put a 200 on it is perfect. I would say 150-175 max. They are Light narrow hills

It will be over powered but not brutally and the weight can be compensated for with a large flotation pod. if you already have the motor and know the history I say run it and enjoy cruising at 3500rpm doing 30+mph getting 4+mpg. I have an 18’ with 150 4000rpm is 23knts give or take.

It will take it

Turn that 19 footer into a 23

You will need a bit more power than that. Merc is making v12 600’s now.

They say with boats you can never have too much horsepower

But you can have too much weight for the size of the boat

 

[SpringVelocity]

Yeah way to big.

 

[InterMechanico]

Alright Alright good for a laugh anyhow!
I'll plan around a 150 maybe 175

any idea how much the boat it self weighs with the volvo in it?
