Beaching mods.

[benniejordaan]

I finally got round to do the beaching mod on my motors.

First, pros and cons to this method.

Pro's
1. You have beaching mod only when you need it, so if you reverse hard out at sea your motors don't trim automatically.
2. There is less pressure on the oil seals and cylinder when beaching onto a steep bank at speed.
3. No serious irreversible modifications to springs

Cons
1. You must remember to release the valve before beaching.
2. Can be cumbersome when getting to it on some boats.

First thing is to find the non-return valve. and then remove it. There is a circlip in place that needs to be removed. Then use a screwdriver to remove it completely. A little oil may come out... not serious, you can top it up when you done.

Here it is! Yours may look a little different,

Maybe it looks like this. No matter, same thing. This is from a Yamaha motor.

Now for machining.
The “T” bar is machined from 10mm stainless steel. It is stepped down to 8mm and threaded for 8mm. The valve is drilled and taped M8X12mm deep. You must be careful not to drill too deep into the valve or it will leak oil.

If yours looks like mine, be careful as it splits and inside is a spring and a ball. It wont come apart easily but if it does finding the spring again may be a problem.

Now simply screw the “T” bar into the valve with locktite.

 

[benniejordaan]

Now replace it and re-fit the circlip.
Note, when releasing it turn it 2 turns and don’t force it when closing it again.

Do not do this in your garrage with a drill. It needs to be done on a lathe by someone who knows what they are doing. But the cost shouldn't be more that about R100 each.

Here is the drawing... Or give me a shout.

Thanks bennie, sweet advice - oh and thanks for the drawing too! Going to get mine done now - finally.. cheers.:

Good one Bennie.

Saw this link on Boatfishing.

Another reason not to make a permanent mod like cutting springs, is that you sometimes need full holding power in reverse.

Like lifting the stern up and reversing your boat off the trailer with the motors when a ramp has a shallow incline

Anyone ever launched out a narrow tidal river on an outgoing tide will tell you that you can't have motors kicking up whilst waiting for the break.

Bennie, I'm kinda forgetful, I'd hate to forget to release the valve and leave my Honda's and transom on the beach.

Hi Foxhat

What did you eventually do re beaching kits for your Honda's?

 

[Foxhat]

I have beaching kits installed and my motors do kick up if I put to much throttle and need to hold position. I just get one of my crew to put their feet on the back of the motors to hold them down. I'm kinda forgetful and feel that if I locked my motors I might forget to unlock them coming in to beach. I flipped my transducers up already beaching, fortunately there was no damage.

I wish the hydraulics on the Honda trim & tilt was quicker, mines dead slow!

I agree they are slow. I have new BF60's on very happy. Was quoted R2500 per motor for beaching kit. I notice that my T&T has a manual relief valve. Will be exploring Bennie's mod. Tx for the response

That's a lot considering all they do is cut the internal spring?

Ask them for the original springs back if they say they replace them.

 

[Joachim123]

I agree Bennie. A bit of a rip off. As mentioned I will be exploring your mod. It pointless paying so much money and still having to have to do what Foxhat does when beaching. I will update once I have decided and completed the mod on the Honda's.

 

[Foxhat]

I don't have a problem with beaching, time the run in,the motors lift when I hit the sand, the hydraulics are too slow to lift the motors and the motors are heavy so you gotta hit fast. Everybody finds something solid to lean against so you don't get thrown over the bow.

Hi, I bought a boat with two 40 two stroke yamahas. The person I bought it from says it has beaching kit..thus motors should kick up. how can I test them before to make sure...do not want to damage the motors....aka just take the sellers word..

I trust they are trim and tilt motors. Be sure that there is no reversing catch engaged (usually only fitted on non- T&T motors). Most beaching "kits" are really just a modification on the little spring that activates a small ball valve. Bennie's mod is a more down to earth approach of loosening the valve override screw.

If the seller did the normal mod, then the easiest (and safest) way is to accelerate hard in reverse and if the motors lift, then the valve spring has been sufficiently loosened. If not, then follow the advice as per Bennie's post.

Hi Guys, I stuck between a rock and a hard place.
Possibly will be locking for someone that can do the beach kit and Skegs. Any recommendations?
