Slower speeds werent bad but higher speeds were a real chore to hang on. Trim is a critical part of steering control.
If the motor is not centered on the boat properly it will cause it to pull hard one way or the other.
Boat pulls hard to the right. You might notice that your boat has started to pull to the right or left after you start getting up to higher speeds making it hard to control the steering wheel and having to turn in the opposite direction to correct the pull slightly. Sometimes this pull is not a slight pull but more of a rather forceful type of pull. Its a new boat to me i have tried adjusting weight by filling the live well which is on the left rear the boat pulls hard to the right and is hard to turn left only a top speed and on plane.
At cruising speed about 18 miles per hour it steers a lot easier but still has a slight pull to the right. I am pretty sure everything is original on the boatcrestliner. Boat Pulls Hard To The Right.
The tab is to compensate for the engine torque. If the Dealer set it dead center its most likley wrong. You still need to eliminate the hard pull to the Starboard side and it should make no difference on the speed of the boat.
It has no effect on rise of the boat only a set of TRIM TABS would do that. As mentioned it is desirable to have some pull to the right so that the boat will be easier to keep straight when a skier is pulling back and forth that is because you will tend to keep the wheel straight by only having to keep some left steer tension in the wheel as opposed to moving the wheel back and forth if the rudder was neutral. On some model motors there is a little skeg sticking down right above the prop.
You can adjust this skeg to counter act it pulling hard to the right. I would definitely check the steering cables 1st. Your prop is probably a right hand rotation set up.
Thats why it pulls hard to the right. If the motor will not put the john boat on full plane it will always pull to the right due to prop torque as he talked about. Most of my 19ft bassboats at certain speeds and trims pulled very hard and you had to hold the wheel with all your might if you let go the boat would do a strong right turn.
This is a non-Whaler question for a friend who recently purchased a used boat. He described that the outboard engine on this 20 boat pulls very hard to the right so much so that even at idle if he takes his hands off the wheel the engine will immediately turn hard right and. 2017 mercury outboard 90 hp 1F904531D and 2B393883 on a 2017 Suntracker 21 foot pontoon boat.
Suddenly motor started pulling hard to the right. Just before this started happening I bumped into a boat dock not too hard and then I was fishing around submerged trees and a boat wave lifted my pontoon boat up and dropped me on the tree pretty hard. If you are completely happy with your lower unit trim and the motor still is hard to get to turn to the left- and if you let go of the tiller it wants to make a hard right turn- then start by adjusting your trim tab so that when viewed from the rear it is full to the right.
Based on what weve just explained if your boat is leaning to the right that is its right side is lower than the left you should point the right trim tab downward. This will lift the right side up hopefully solving the issue. Play around with the angles to achieve a balanced boat position.
Bought a newer boat and put my motor on it Its a 14foot smoker and the motor is a 20 hp mercury. Took it out for the first time and noticed it really wanted to take the tiller out of my hand and turn the boat to the right. Slower speeds werent bad but higher speeds were a real chore to hang on.
Any thoughts would really be appreciated Thanks. Mechanical systems include the rotary and rack and pinion steering systems found in smaller boats especially outboard-powered vessels. They use a cable or cables that extend or retract when you turn the wheel.
When the cable extends it will push the motor in one direction. When it retracts it pulls the motor in the opposite direction. Or is it happening while the boat is sitting at rest.
Lets go over some of the reasons that will cause your boat to lean to the side. If your boat is leaning will at rest this is often because of a weight distribution issue either from storing gear or passengers more to one side then the other. In my experience reading this forum and others just about all 175ft glass boats in all brands have this problem.
Most of them run between 75-115hp motors. Some people try to correct it with weight distrobution hydrofoil motor height prop size etc. What most people end up doing myself included is start the trimming up.
The torque of the engine and propeller makes the boat want to go to the right which causes the steering wheel to pull hard to the right. To compensate and keep the boat going straight you have to grip the steering wheel tightly with both hands try to turn the wheel hard to the left and pray that you win. Trim is a critical part of steering control.
The tork of the prop turning will make the boat pull hard to the right. Trimming the motor up will relieve a lot of this tork. To trim the boat out properly you need to power the boat to plane Trim the motor up to the point just before cavitation prop drawing air or comming out of the water.
If the boat is regularly run trimmed in the tab should be rotated to point to the same side that exhibits the steering pull. On almost all single engine boats operated with engine in normal trim position the tab should point toward port when viewing the boat from behind. This will help eliminate steering pull.
Brief Description of trim tab and how it affects the performance of your boat. If the motor is not centered on the boat properly it will cause it to pull hard one way or the other. It is centered properly.
It was ran on another boat also centered properly and still pulled the same way. Nov 14 2007. I have a 14 v-bottom boat with a 20hp Johnson that runs and steers great.
We tried a Chrysler 25hp motor on it a few weeks ago. The motor runs great but it pulls so hard to the left making the boat steer right that it wears me out after a few minutes. There is no adjustment fin on the lower unit.
Sailors began calling the right side the steering side which soon became starboard by combining two Old English words. Stéor meaning steer and bord meaning the side of a boat. As the size of boats grew so did the steering oar making it much easier to tie.
Second the thing pulls HARD right when underway. Let go of the wheel at any speed and it just tears the wheel to the right. When you hold the wheel straight and get on it the boat gets all squirrley.
Third which the dealer says is normal is the loud harsh engagement of reverse. Seems like the trans and drive are going to come apart when kicking. It has a 30L IO Mercruiser - on plane the steering wheel pulls to the left and is very hard to turn to the right.
At slower speeds it steers just fine. You can let go of the wheel and it tracks straight. If you have a hard time keeping your aircraft straight on the runway or it pulls to the opposite side its supposed to adjust the value for engine_wash_on_roll in flight_modelcfg.
If its negative the plane will pull to the right positive will pull to the left and zero will make it go straight.
