Hey friends, I'm new to the forum and needing some help if you'd be so kind!
Just picked up an older Nitro 17.5 foot with a 1996 Mercury Force 120. The engine runs fantastic at idle and seems to shift properly. Now here's my issue: When I put it in forward gear and begin accelerating, the motor barely reaches (approximately) 20% of its rpm capability. I put the motor at WOT and I'm barely moving 15mph at best.
To try to troubleshoot it, I beached the boat and removed the motor cover. Manually operated the throttle at the motor and it had no problem reaching a screaming high healthy RPM. So it's only in forward gear that this problem is occurring. What are your thoughts? Thanks!
