First run of the year at above plane 3500 RPMS started getting a low block pressure alarm and RPMS dropped. Checked all pickups and no blockage.

Yep I’m in. Water pressure threshold is low . How many hours? Stock impeller? Have you parked on sand bars but had to back off?
It’s under warranty so let us know.

We only give free advice when it costs you money. No guessing on free stuff.
In sure is a sensor or the impeller. What did they do for your winterization.

Nice , and no downtime.. letters are easy and gelcoat is fixable so your on your way to a “ pre disaster season”. Easy

A word of advise.
Never approach a dock faster than you want to hit it
