No, not rev limiter, but that sort of effect....tech literature gives max RPM as circa 5700rpm IIRC. It doesn't happen at any particular point on wave etc. and only at WOT.....power back a little and goes away....
I was sure i'd read about this on a boat forum (hence the 'blow out' query), but buggered if i can find it.
We opened up to WOT on the final run in to the estuary as it had flattened out and allowed...tide was on a strong ebb (not that I think that has any bearing).
Strange one...going to run out with the 19 tomorrow and see if it still happens....I'm leaning towards it being the prop casuing it as no engine faults and it ran faultlessly otherwise.
If cookee or another pefromance ribber is looking in, is the 'blow out' something the racing guys struggle with or did i imagine that too?
