Author Topic:   On plane

Seeking advice on how to get up on plane while staying within restricted speed zones. I have a 17 foot Super Sport Limited w/ 100 hp Evinrude and on the Charles River or Boston inner harbor where they enforce the no wake zones, and my bow rides high. I can't get it level without fear of a scolding, (they at least let us stand up.) In open water I have no problem getting on plane. I've seen "fins" on outboards wonder if they work.

Not possible! Slow speed means slow speed. Jetskis don't hardly make a wake yet they can't go fast(legally) in no wake zones.

I should clarify, I know I can't get up on plane in a no-wake area, but it seems it takes my Whaler a long time to get up on plane when I can open it up. Even when I'm trimmed down it takes a while to get up. Now is this normal or is there a way of planing earlier.
I re-read my note and expected rash of sarcastic replies. I appreciate you all letting it go anyhow the question remains, do the "fins" help

How long does it take you to go from idle speed to cruising on a plane? What is the slowest speed you can go and be on a plane?

Bosmass, what year is your Evinrude 100?

Highwater... I don't know but I will time and record that information this week-end if the sun ever makes a New England appearance.

Bigz.. 1989..why?

That boat should pull so hard you better hold on. Something aint right and personally unless you are one of those who likes to see if their boat will plane at 12mph, the fins don't really do much except slow you down. I personally do not run one and have taken them off both my 15 & 17's but that in itself is another topic. Look for posts titled doel-fins or whatever and you will get a better idea. Did not mean to flame you, was just stumped by your question.

You definitely have a problem too much weight "water ingress" or reallly sick engine. I would have a compression test done, also check prop. What is your RPM at WOT? Weigh it if you have to.
A friends supersport with an 85 is great.

Bigshot, does that mean with fins I'll be able to plane @ 12mph? I'm not one to jump waves and top end speed is less important than a comfortable ride at lower speeds.

Oh Brother!

I don't know but I can plane at about 17 without one and that is so unefficient it is puzzling. If you want to get good mileage, get a smaller, lighter engine like a 60 Merc or zuki 50hp 4 stroke. Will still do upper 30's and you will laugh at the gas pumps. That 100 is a thirsty motor but a great engine that will make that boat haul booty. You should be running a 19" and doing close to 50 WOT at around 53-5500 rpm's. If not, get it looked at.

I had Doel fins on both my Montauks (17', one with 90 Evinrude, one with 100 Mercury) and also on my Outrage 22 (Evinrude 225) until I installed trim tabs.

The Doel fins helped get up on plane at lower speeds, smoothed things out a little at top end, and I could not detect a loss of speed.

I don't know if they would get you on plane at 12 mph, but I doubt it.

A Doel fin will help you get on plane quicker and at a lower speed. I seriously doubt that you would be able to GET on plane at 12 MPH. I believe it might be possible to STAY on plane at 12 MPH once you've accelerated enough to actually get on plane. It would help to have some weight in the bow also.

If you are talking about keeping the bow down at slow speeds in a no wake zone, try shifting some weight forward.

To continue with the way this thread is heading repower. Get a newer lighter engine, it is possible that the 89 Rude just does not have the HP anymore, even with less HP you might be able to get up on plane sooner.

I dont know the laws where you are, but in LBI N.J. if your at plane in a NO WAKE ZONE,you can count on a fat ticket.I look at NO WAKE ZONES as a time to gather my thoughts and enjoy my surroundings cause when I hit the last bouy I'm WOT.

Stephen....everywhere on LBI you are gonna get a fat or boat. Driving from Cedars to Beach Haven is like riding the Gauntlet.

Follow up:
All advice was read and digested, and I've concluded that I am just getting to know the boat and the motor and my expectations of getting on plane at low speeds is ridiculous, but this comes purely from lack of experience. I did shift weight and that helped, especially in the Charles where they enforce a 6mph limit. Again, it is getting to know not only what it can do but what it does in various situations. The Evenrude 100hp is more than I need and plan of repowering with a smaller, more efficient motor. Financially I'll need to wait till the end of the season when the "SALE" signs are posted. Thanks for your comments.

PLEASE be aware of the difference between a "no wake" zone and an "idle speed only" zone. As far as wakes are concerned, you're much better off to go ahead on through at full speed than you are to slow down and plow along throwing a 3 foot wake. If you're going to slow down, then go ahead and pull it all the way back to idle speed. It never ceases to amaze me how many boats crawl past our dock at something between idle and on plane, thinking that they are being considerate. By that, I mean if your bow is "up" at all, you're displacing a lot of water and you're plowing. Here in Georgia, boats under 26 feet are encouraged to just stay on plane through most of our "no wake" zones because their wakes really do a lot less damage that way to docked boats, etc. I sometimes wonder if people think that the sign that says "Please watch your wake" means that they should turn around and watch a three foot roller crashing into my dock.

Tight Lines!

Good point Offshore, actually the signs should probably say, 'Minimum Wake'. I too have seen a lot of boaters pull the throttle back, let the stern mush in, then maintain that attitude in a 'NO WAKE' zone. They would create less of a wake on plane, and I have seen some tickets issued for boats going too fast in a no wake zone!

That sounds like a "officer discretion"judgement all thing,if he's in a good mood,no big deal if he aint,ticket time.Probably a good money generator
