i recently bought a boat with a 2005 yamaha 115 4-stroke m# 115 TLRD. it states in the owners manual the rpm range is 5000 to 6000. should i feel comfortable in running 6000. right now i'm proped out about 5800 rpms. 6000 sounds a little high to me. heck even 5800 seems high. what do some of you think.
