Hello,
its been a long time since i last ran a boat or posted ,i picked up a ready to run Manta Ray yesterday and have a couple of questions .
Its fitted with what i think to be a spd drive ? but can anyone tell me what version ?? also anywhere in the Uk i can get a spare flexy ? .The engine is a Zen 23 but i was told by the vendor its a modded motor ? says ez 23 with a red spot on both the pull start and cylinder head ?
The boat is in great shape but came with an open un muffled exhaust that i have replaced with a Prestwich pipe and homemade header, lastly its got a water pump something i have not used before and was wondering can it be tested without putting it in the water <lake is frozen>,
cheers Euan.
ps i will add some more photos in a bit
