Forgive me if this is in the wrong forum. I’ve posted in the prop section too but I’m really not sure where it belongs
There are a few things going on. I suspect related but perhaps not.
This is on a 28’ regal express cruiser with twin merc 4.3 with alpha one gen one drives. Motors run well. Drives got me impellers and oil in the spring.
1. On the port side when the drive is trimmed all the way down I get a vibration when I’m under way. If I trim it up a bit it goes away. It goes away equally if I trim both sides up together or just the port and leave the other alone. The vibration seems to go away regardless up around cruising speed but perhaps I just can feel it any more.
2. Recently the water was low in the river I dock in my prop hit mud and stalled the engine, I can’t remember which side it was unfortunately. It was vibrating before this happened.
3. Some of the time (especially today) when I accelerate from headway speed the stern just sinks down and the engines rev but I just drag *** and can build up speed.
This was not the case last year or for my first real run this year. It seems to be getting worse although it seems to be somewhat intermittent (I’ll try again in the morning and perhaps it will have stopped being intermittent).
4. My trim tabs have stopped working in a bow down position.
Any thoughts about what’s happening? The boat stays in the water, I’ll get in there and do what I can. I hope to not haul it.
