Wiseco forged replacement OMC 49.9 Mod-50 pistons are now available. They are improved versions of the #10908 previously supplied by the late Phil McDaniel. Designed for use with the Mod-50 or RD-series (40HP) long con rod, these pistons include a .120 top ring land, pre-machined boost and finger ports, plus hard anodized pin bores and fire dome. Each piston kit includes wrist pin & retainer clips and steel keystone rings. Size offerings include standard (3.000 bore), +.020, +.030, +.040, and now +.050 oversize. Pricing is $135 each.

Good morning guys. Looking for a set of velocity stacks for a 95 OMC 50 twin. Thanks, Bobby..
Breaking news: +.065 oversize Mod-50 replacement pistons now available!
Wiseco just approved manufacture of +.065 oversize pistons for the 49.7 CI OMC loop triple. This means you can breathe new life into run-out or damaged +.040 blocks, creating a 51.9 CI monster! Bore sizes now available include: Standard, +.020, +.030, +.040, +.050 and +.065. Notes:
1) The +0.065 piston is legal for APBA 850cc Mod and NBRA Super-E classes which share a maximum +0.070 bore size. Minor file fitting of +.065 piston rings required.
2) Pistons require use of OMC Mod-50 (3/4 pin bore) or RD-Series 40 HP (5/8 pin bore) long connecting rods. Skinny needle wrist pin bearing conversion kits are required for the 5/8 pin bore RD-Series 40 HP connecting rods.
3) The Mod-50 replacement piston includes a flat top fire dome design that requires use of the 70 HP service cylinder head with pocket style combustion chambers.
Commitments through June 1 will be at the introductory price of $135/piston kit which includes the Wiseco forged aluminum piston with hard coat anodized pin bores & fire dome, wrist pin & retaining clips, and semi-keystone steel piston rings. So dont delay; place your order now!
Best of luck with your engine projects,
Tim
