Hi All,
Just wondering if anyone has any ideas on the engine vibration we're getting. I've noticed it a bit more over the past few months. It cycles on and off on with a regular rhythm. It lasts maybe 3 seconds, goes away for 3 seconds and then comes back for another 3. I do notice it happens more when the boat rolls from side to side. I just pulled the boat, did the bottom & replaced the zincs thinking the zincs might have corroded in a way that would throw the shaft off balance. The cutlass bearing was tight with no play & the shaft spins easily by hand with the engine in neutral. I haven't checked the the engine alignment or the motor mounts yet - that's my next task.
The boat is an E35/3 with a Universal M35A 30hp with a 15 inch three blade Maxprop. The boat cruises easily 6.4 knots at 2200 to 2300 RPM.
Would appreciate any suggestions.
Thanks to all who respond,
