82 20 foot info

[McGillicuddy]

Welcome aboard Mikem...
Floors, scuppers and transoms are the usual problem points. Assuming the scuppers are 1 inch brass tube thru hulls, draining out the bottom of the boat - they tend to separate from the hull at the flare, and allow water to seep into the wood blocks that support them. You'll notice water in the bilge after a good run or even if its sits in the water a couple of hours.
That can be spotted by noticing a stream running along the out stringers or cracked/corroded brass tubes.

Floors can be soft if they've seen too many screws, and likewise with the transom.

Regarding power, I think 115 to 150 hp is plenty, but the key thing is weight. the 20' hull was designed for 300 lbs of motor or so... I assume that holds true for the '82s but some one make correct me. Yami 130 - your golden...
Some guys are repowering with 90hp Suzukis, etecs and even optimaxes and seeing incredible economy cruising low 20s and topping out mid 30 mph.

I don't know about 250 hp, but with 360 lb 25" shaft 1983 chrome bore 2.4L Merc 200 w/225 carbs - with bait tanks, batteries and butts forward - you'll have your own "Flying Machine"

Shoot, you'll be doing skateboard tricks in 4' seas

Good luck with your new purchase should you succumb to the sickness.
