Default Opinion on getting on plane

So when I sold my boat last October I was on the sea trial and had just left the harbor and, as I usually do, pushed the trim tab switches down then eased the throttles up until she got up on plane, advancing the throttles slowly but steadily and enough to keep momentum. It was on a 2004 Regal 3560 with bravo 3's which is a fairly stern heavy boat in my experience. The guy that was buying the boat commented that easing the throttles up was not the way to do it and he preferred to pin it right from the start which he said didn't make the engines work as hard because it didn't plow through the water as much and got on plane faster. I certainly prefer my way of doing it and I don't really think there's a universal correct answer but I was curious to see what anyone else does. Ease them up or pin it to win it?

I pin the throttle to the max... as it's breaking over I ease back on the throttle, work my trim and tabs until i'm at cruising speed.

I think there is an in between. Jamming the throttles seems wrong, but not sure driving miss daisy is necessary either. Never really thought about it, just seems to happen.

Pretty much max power until the boat is over the hump then ease right back - I can't see the point in pushing a load of water around.

This assumes the engine is warmed up a bit

I like to pop it up on the step with a good bit of throttle. Too much strain on the motor with slow and easy.

No need to nail the throttles, but get it up quick enough for the bow to come down you so you can see where you're going in a reasonable amount of time.

I don't usually put the trim tabs down until I'm on plane. Then make slight adjustments with the trim tabs.

If I remember I put my tabs down, trim at about 2.0 degrees which is how I am set for idle in no wake zones to prevent the boat from wandering. Then I push it up to about 90% and it pops on top and as it comes up on top I reduce power to match my intended speed. Outboard Opti 150, boat is a BW, kinda heavy but still good power to weight ratio so it gets up on top fast. The Rev 4 prop seems to elevate the stern and helps a lot.

I don’t slope it off of the bat and I don’t take 10 seconds to reach full throttle. I would say I ease it up to full throttle over 5 seconds or so. Not super fast not super slow just steady.

now I will say that before I start moving the throttles to Mac I do generally get her putting along at Hull speed before I start to increase the throttle.

keep in mind my boat is a 37 footer so it may be different for smaller and lighter boats.

I don't think pinning the throttles when coming up on plane really stresses the engine much in particular, as long as you back off before as your reach your desired RPM. Don't forget that boats don't have gears like your car... When you pin your car's throttle you immediately red-line your RPMS in low gear and basically keep it red-lined until you get going fast enough. On a boat, opening the throttle all the way when you are standing still admits the maximum air/gas mixture into the cylinders, but the RPMS will just increase as you actually speed up. You will get an immediate bump in RPM as the props start biting (and before the boat really moves much), but that's actually helpful as it puts the motor into it's higher torque RPM range so you should actually push past the transition point more quickly.

most modern day electronically controlled engines/throttles are going to likely limit the acceleration

i do things a couple ways depending on the situation...

if i have visibility and no obstacles, i usually let a boat plane before applying tabs

if i would lose visibility (i.e. in lower helm) and there are obstacles nearby, i usually set tabs immediately after throttling up

it takes some seconds for a boat to plane / reach max RPM, so that gives you time to tweak where you want to end up, some times i pull back on throttles right away to get to cruise, some times i want to exercise the engines so i run WOT for a few, if conditions allow

of course there are other variables such as weight on-board (i.e. gear and people) and distribution of said weight, so you have to be more on top of settings the tabs or may even need them to achieve a plane.

I don’t see commercials/professionals slam the throttles often. I think they know and depend on their equipment

with my twin Outboard’s and Boat. It has no bow rise which is nice It’s a cat but half throttle and she just rises up

maybe fat heavy inboard boats are different. Don’t have much expience owning. I will have to ask my inboard friend who has 1800 hours on a 33’ searay
