prop question, do rpm matter?

[eggsuckindog]

Confused here when you say "smaller prop" the smaller prop should give less cruise speed and more RPM at WOT and should plane quicker???

running the correct pitch prop will allow your boat to plane quicker - think of it like this: you're driving a stick shift vehicle - you attempt to start off in 3rd gear - what happens ? same thing occurs with a boat engine,with way too much prop pitch.too much pitch,the boat's a dog outta the hole - no lift

as far as rpm is concerned:
think of it like this,you're running the engine on the hose - you "rev" it - the rpm climbs quickly -right ? runs and screams on the hose - right ? no load on the engine.for max engine durability,you want that engine to hit it's max rpm,with the boat loaded,as it's noramlly ran...there's a reason an engine mfg puts this reccomended range on an engine - that's where they want it to run.

it's all about "load" ...
