I'll produce more oem 155 pumpshue for sj this winter - same yamaha oem style - no rubber ring

All summer i have tested one on my rickter fs2 5mm stroker - after having to work hard to enlarge the intake duct(was design for 144) to fit and align the pump/pump shue and engine ( because with 155 pump - you need a 10 mm longer shaft for full splines engage, also pump is larger in diameter and then your shaft on pump side will be lower than 144 so will enter the hull on more angle - so you will need to lift a bit the front of engine to be all aligned) - so after all this trouble - 155 with right impeller is super

You have to use sealant between wear ring and my pumpshue - and after final alignment and sealed - when you want to work on pump/impeller leave the wear ring in place and all will be easy to reinstall - so you need to have the blaster 2 style 8mm long bolts and blaster 2 wear ring with treads on it for long bolts
