I have a 08 Suzuki 140 HP it was over hauled in San Diego with a New Short block, Engine holder, Oil Pan etc,,,Now My Boat is on Kauai I notice Oil Film on top the Cavitation Plates and checked the oil dip stick and it showed half oil then I started the motor on the trailer and ran it 15-20 minutes turn off and checked the dip stick and now it only shows a 1/4" oil on stick! were is oil going? The work was done by Suzuki mechanic at Shelter Island SD ! I took off the complete Cowl Panel and saw no leaks at all so what should I check for? The Oil filter and cooler look new! I can remember if he put a new cooler but it looks new! Any suggestions would be appreciated! Mahalo Happy Holidays Thanks
