Wot

Hey i was just wondering: Is it bad to fly around in your boat at WOT for a good 30 minutes to an hour non stop? (i know its a dumb question but i need to know because im usualy going full throttle from one point to another) Thanks

I am curious to the answer aswell.

I work on the principle yes, isn't that why I service it every 100 hours & don't expect 60,000 miles out of it. More important is not to turn off immediatly after such a run. Usually I would back off as I approach my destination, let things cool down.

Yea i would think that engines are made to withstand more than WOT because, for example, if you have 6 people on the boat thats a lot of wieght and the engine should be working more, therefore i would assume that the engine should be powerful enough to be at WOT with max capacity and not be stressed..just my thought tho heh

Unless your manufacturers manual specifically says otherwise it should not be a problem at all, marine engines are often run flat out for longish periods and as such are designed for that!

I think that the manufacturers will have done alot of work to ensure that an outboard will run at WOT and give a reasonable engine life, however to run constantly above WOT can only be asking for trouble. Note, if the weight of the boats load is increased then the the pitch of the prop should be reduced so the engine can again reach but not exceed WOT, this will provide the best performance and fuel consumption.

Exceeding WOT or overloading the boat so the engine doesn't reach WOT is only asking for trouble, stick to the engine manufacturers recommendations.

I do belive you are confusing WOT (wide open throttle) with max revs.

You mean that you can run the motor BETWEEN idle and as far forward as the stick goes?
I always thought my boat only had two speeds, stop and flat out!

I always thought the same - stop:go / on:off

....... and WOT meant " wot about fuel consumption ?? "

I'm led to believe (whether this is correct or not) that performance engines like the optimax actually prefer to be riden 'ard if you'll pardon the expression and don't like it too much when they are idling for long periods of time.

Personally apart from where I'm restricted on speed I go flat out everywhere!
