Thanks for the info.
I am about to put the new RIB in the water for the first time this week (Tide, wife and work (extra hols) willing).
Completed all usual checks today, but couldn't get water from the tell tale!
Had a good luck around, and the only outlet I can see (on right hand side when looking towards rear of RIB) is via a tube that eventually leads to the top of the carb (looks like part of emmisions control)?
I can blow through this so it is not blocked.
Engine water intake looks clean also.
Daft question, but is this the tell tale?
[or part of engine mixbreathing/combustion control?]
The engine was run with mufflers and a garden hose at tick over revs possibly increasing to 2000rpm tops with full tap pressure. Not other signs of overheating/engine distress.
No other issues with engine.
I guess my query is: will the tell tale appear at increased revs and/or when travelling through the water. Or is my daft question not daft and this is not the tell tale?
I have another RIB with a 40HP 2st Mariner and under the same conditions I get water from the tell tale.
I am looking at water impellor inspection/replacement.
Thanks in advance for your shared experience.
