I have just picked up an old square nose 94 sj it has a 650 in it and seems to start and run well dry but took down to the lake today and it just bogs down and wont accelerate at all. Also steam coming from pisser and water only seemed to come out when first switched off.
Any ideas on what I can do would be much appreciated.
