I think a ‘clinic’ or gatherings for OBM owners would be good. We can share our experiences which can proved to be invaluable, especially when you are stuck in the sea with a ‘konk’ OBM. Count me in, should the “clinic” works out.
If I may suggest; the “clinic” be held at the RSYC in Port Klang, since I’m a member of RSYC & they are open to public too. They do have classroom facilities, pontoon facilities, F&B with excellent taste & reasonable priced food if we do get many ‘kakis’ to come join the clinic. Otherwise we could just meet up there & talk about OBM, boats & of course fishing.
Lets see how things work out. In the meantime I will talk to RSYC of our intentions. I live in PJ & go to Port Klang almost everyday. So can meet up either place anytime for yum cha, etc, etc. Just calling2.
Cheers.

I think among us here, you are the only one with mechanical experience to take apart and put back an OBM. Suggest that we have a clinic on general maintenance and minor emergency repairs. Your opinion, please.

Bro,
I think you mean brass not copper!
There several types available - brass, copper, aluminum, mild steel, stainless steel depending on the welding application. Hantam sajalah whatever material it is, as far you got spare shear pins… hahhahaha

I had a bad experience with shear pins, years ago. In fact, I wrote about it in my book (that chapter on Bera).
We ran out of pins: the boat was too heavy for the 2hp engine, and there were lots of snags in the Bera river. Then Meng started using nails. Problem was, the nail is slightly larger than the original shear pin. Filing the nail was too time consuming. He decided to force it in…
Result? Enlarged shear pin hole. Now the pin (nail) start vibrating, and just break on its own accord after a while.
That’s why I’m looking for ori shear pins. Unless they are damn expensive lah! How much ah?
Wahoo,
Correct me if I am wrong but isn’t shear pins also known as “cotter pins” in the olden days? Made of brass and available in different diameter. Usually obtainable from hardware shops or engineering hardware shops.
Are they the same application or do the ones for OBM have a different specification? If so, then have to get them from OBM agent shops.
JB, I remember that from your book. but you never reveal anything regarding the shear pin hole becomes ‘too janda’… hahaha
Those cotter pins are made from hi-tensile steel, meaning they are made to be easily broken upon impact. Of course la that one is to protect the rotating components. if the shear pin is too strong, the propeller, shaft or drive gear pulak yg might get damaged upon impact. small damage to prevent major repair mehhh…

Shear pin is made of brass and is different from cotter pin. It is about an inch long and is cylindrical in shape. The function is when the propeller hits a hard object, it will break first to save the shaft.
Cotter pin is a piece of soft stainless metal bend double to hold the propeller in place. The bend part is round and hollow so as not to pass the hole when it is inserted. The two ends are to be bend backward and away from each other. It is semi cylindrical and when folded the two make a piece of round wire. I think you make an image search in google and that explains better.
The difference is:
If a cotter pin breaks; you will get into bigger trouble, bcoz a cotter pin is NOT meant to break, to protect.
A shear pin is meant to break, to protect; & you will save heaps of money from further damages to any mechanical equipment. It’s meant to break upon high stress to a moving part or rod, & thus relieving the parts/rods from further damages.

Got some feedback about the DF6. Seems that, the cooling system “piping” (what do you call it ah?) is rather small. So, if you use th engine in say shallow lake areas with lots of loose catttail plants, the thing may get jammed up easily. Either you be extra careful, or enlarge (janda) the hole.
install a radiator la… so that the engine has it’s own cooling liquid which circulate internally, not using external fresh water… no external water intake, no choking hazard… hehehhe
I was thinking if we put a fine wire mesh (strainer) on the water inlet port, it could help to resolve the issue, but I never tried it before.

I suppose it happens to all makes of OBM. The inlet hole is more or less of the same size.
Just imagine instead of the dirt getting inside, the fine wire mesh will go in first. Or the fine wire mesh so messed up with dirt it closes up the inlet hole instead. Hehehehehe… just joking and in theory only. Wahoo’s suggestion may be practical.
Alternatively, dont fail to raise up the unit when it comes to the shallow or places with lots of moss or weeds. Bring along a piece of hard wire or a lenght of tennis string (best is guage 14)to clean up the whole whenever necessary.
