Have a 1977 25Hp Johnson mod#25E77S. Runs fine at slow speed, if I give it the gas all at once the motor revs & we don't get forward motion. My first thought was the shear pin, pulled the prop & all is good. If I give it the gas slow & steady it runs fine, & the boat gets up on plane & gets to top speed with no problem. From slow speed if I give it the gas all at once it acts like a stick shift car when the clutch is slipping. Thoughts?
Thanks, John
