just bought a starcraft fishing boat, has johnson 35hp electric start, not tiller, long shaft. i thought exhaust was thru prop, but has two holes in front of center leg section, exhaust is coming out here. i'm in a barrel of water in back yard, is this correct or do i have a problem ?? runs great, no other problems that i can see, want to go to the lake, thought maybe i'd ask this question first...... thanks, elmo
