Unfortunately our ZF 15 MIV transmission needs replacement. The current gearbox has a 2.13:1 gear ration and I believe the gearbox has been replaced in the past. The owners manual for the LF38 says the ration should be 2.83:1. Our prop is a two blade 16" x 13" x 1-1/8" RH which more closely matches the specs for the LF35.
Can any LF owners confirm their transmission ratio. I'm not certain that our gearbox is correct, and if we're purchasing a new one, it will be good to get it back to standard. We get along OK with the current setup but the performance is not outstanding to windward. Tony Mitchell SV Irish Melody, 1983 LF38 #150 Vuda, Fiji
