Don’t know about 70’s thought at least 1980 to 1990 as for trailer it dose support where it’s neant to support it has rollers front and middle of trailer and the rear of the boat is supported by fixed flat bunks either side and it’s not to small for the boat at all as for the twin axle in my opinion...

I used to do 50 - 1 on my mariner 40hp before don’t know why they say 100-1 yeah all in pretty good condition to be fair , in another note when was this boat made or finished production just curious , also bought some Mini cooper alloys for the trailer because don’t like 10” steel wheels .

Thsnkyou for letting me join , i bought this boat with 2 stroke 60hp yamaha outboard and double axle trailer i paid £500 ? good deal or not ? needs a full interia and steering all in order now thanks in advance
