Bleed restrictors debate - do they really impact performance?

[hempfarmer]

Hi everyone,

I am hearing mixed opinions on whether they make much of a difference. Just realized I am missing all of mine and told by one person it could be having a significant impact on performance. (especially take off when towing - boat tends to stall if I punch it under 1200rpm) I am then told by another person that they are not that important and if anything you would only notice it at idle.

'80 Merc Inline 6 115hp

Curious to hear your opinion!

Best regards,
Russ

Only used at idle. They may make idle a bit smoother. If your boat stalls when accelerating, it is likely the idle mixture screws are a bit lean.

Yes if missing and you idle a long way, they can cause stalling/bogging as raw fuel is thrown into cylinder fowling plugs. People try to correct the engine from loading up by adjusting/leaning the idle mixture,thus making mixture to lean and causing futher accelleration problems....

Thanks, I am interested to see what difference it will make on the water. Also hoping the new ones stay in place and not something I have to check on every year.
