+1mm (29mm total) stuffer stroker crankshaft for marine engines. Full-circle crankshaft reduces case volume, increasing primary compression and increasing power.
Feel the additional power that can only be obtained by increasing the cc's of your engine. This crankshaft features a 29mm total stroke (up from the stock 28mm stroke on Zenoah marine engines). Fits Zenoah G231PUM/G260PUM/G290PUM/G300PUM etc with minor crankcase modification - you will need to slightly carve out the cases under the crankshaft flyweights to allow for proper clearance. Installing this crankshaft has a significant performance gain for the Zenoah engines.
