Just got it back out of the shop after having replaced the fuel tank to get the carbs cleaned...had to give the baby a bath
Replaced the "swiss cheese" instrument panel as well.

Boat is looking great !!!!!!!!!! do you have nay numbers on speed for the old 200 ... an what prop... i may be moving over to one of those...

performance
 

finally dodged the wind and rain and got it back out...so to answer your question on my gps with 25 gallons fuel, my wife and myself (300#s combined) and a normal amount of fishing gear..
speed was 51 mph at about 5700-5800 rpm (max rpm)

i am thinking may build my old merc and hang it out back !!! Thats moving pretty good !!

Prop size
