Re: Brake design ideas?

Sounds interesting swamper2, I have lots of power trim units around. I can't seem to open the pic, could you pls try again, or I could send you my direct email if that is easier?

Snow bullet said he would take a vid of his set up, if he is ok with it I can share it with others.

Hello snow bullet, any chance of getting a pic of your brake pedal and cable set up?

Thanks snow bullet, is it a cable that runs from the foot pedal to the arm out back?

Re: Brake design ideas?

Hello snow bullet, would I be able to get some pics that show how the brake bellcrank is set up? Is it foot, or hand operated?
I sent you a pm to see if we could take the boring part of this off the forum.

Re: Brake design ideas?

My last hull had two snowmobile carbide ski runners mounted 1/3 the way forward from the rear. It did a good job of stopping fishtailing on glare ice and you didn't notice them on snow. They were a PIA trying to park on shore if there were any rocks, or park across a wooden dock because the carbides...

Re: Brake design ideas?

Thanks folk's, I am getting in touch with them. FYI to those who are not familiar, a ploy covered hull on glare ice slides where ever it wants to. There is no directional control and it is a full time job to just keep the bow out front because the weight in the rear wants to swing the back around. I...

Re: Brake design ideas?

Thanks for the advise folk's. I should have probably termed what I am trying build/buy as more like steering brakes than stopping brakes, although hoping to get both from the same device. Where I have to travel I need to snake through a few narrow channels and without something to keep from sliding ...

Brake design ideas?

Finally getting around to finishing up a new to me 13' aluminum hull that will only ever be used on water/ice and snow. One of the requirements I have is to make up a brake that can be used to reduce fishtailing/spinning out and to hold the boat in a stopped position when parked on glare ice. Curren...

Re: California Airboat

My poly was 3/8" and would have been better if it was 1/2" in terms of adding structural strength. It was held on with 5/16" elevator bolts that had 1" flat heads. Chunks of ice is like boulders and is real hard on it. Had we taken it easier with it I believe we would been able to keep it going a lo...

Re: California Airboat

Yes it is an Aircat. This was my first airboat, mine had an 0360 for power. I used it extensively on ice and frozen rivers to get me to my home. I added poly and some addnl stringer support and it held up well for 7-8 years. The stringers eventually gave in from breaking thick ice while carrying hea...

Re: Lenco trim tab fix

I need something at the transom to provide braking and to assist steering on ice. The cold temps might be hard on the plastic and so ...

Re: Mounting cage to hull?

Great idea Gary S, it makes a nice tight fit, it welds in real nice and will be more flexible than a heavier slug of pipe. I used a piece of steel pipe yesterday and as Whitebear said it was difficult to get it up to temp to weld without overheating the conduit. Thanks gent's, the answers seem to al...

Re: Mounting cage to hull?

Thanks for all the advise.
If anyone is still watching I have even more questions. I am unable to source 20' lengths of EMT and I need 2 pieces 14' long at the rear. Is it acceptable to butt join the pipe and if so, should I find something to slide inside both pipes at the joint to give it strength?

Re: Mounting cage to hull?

Thanks Whitebear. So would a 3/8" bolt brazed into the end of the pipe be strong enough and is it simply welded to the inside of the pipe, or outside the pipe?

Hello, I am in the process of making up my first cage and I was wondering what most folk's use to mount the cage to the hull? My hull is aluminum so I will need to somehow bolt it to the rail. I have seen where a threaded rod is welded into the end of the 1" cage pipe and it is bolted to the hull. I...

Stand a beer bottle up right on a table. Put your pointer finger at the part of the bottle where it starts to neck down and push as you would slide the bottle across the table. Each time you push the bottle move your finger down toward the bottom of the bottle one inch at a time. Notice the differe...

Re: Engine mounting height?

Thanks for the help gent's, I wasn't looking forward to taking the engine off the stand again.

So loudmouth I'll bite and if I have been set up I'll laugh too.... how would the lower prop increase thrust? I have been thinking it would significantly reduce thrust.

Engine mounting height?

Hello, I have read on the forum that an engine can be mounted 1 beer can below the transom and 1 beer can forward from the prop tip, so that is what I have been trying to fabricate my engine stand to. After extending my front stand legs 4" and leveling the engine, I am 7" below the transom. A little...

Thanks, not knowing much about the set up I was assuming the vibration would have been less if it wasn't attached to the engine stand.

Most of the cages I see on the forum are attached to the engine stand and I was wondering if there was a reason for this? I have lots of space for my prop to swing if I build the cage so that it only attaches to the hull for easy removal. I would also make up a couple of removable shields down low t...

Hello, I have just removed my engine for the first time from the stand to do some work on it. As I am sure they all are, the four bolts that run through the rubber engine mounts had nylock nuts on the engine side of the mount. I noticed the engine block is concaved where the nut tightens against it....

Re: Leveling the engine and engine stand question

I have another engine stand question if anyone is still reading the post.
I read about people adding washers to fine tune the engine height based on trim/ride. Where would the washers be added such that they would raise/lower the rear of the engine?
