Nice boats, haven't seen a tether boat, or car "in the flesh" in a long time

Ohlsson 60 - CAM


Hi guys,
Is there anyone who could sell CAM timing (sheet with contact) for Ohlsson 060?
I have one engine and a CAM there is missing :-(

I am not sure what part or parts you are looking for. here is a parts list for a O&R 60 engine, does anything on it look like what you are needing?

The cam on Ohlsson's is a flat ground on the crankshaft. There is a window in the front bushing where the point arm runs on the crank.

Hi earlwb,
I did not have the right information, this part is #1025 and is called a moving contact point. Thanks for answer.

For Mr Wiz, Bill, Earl, Corio, Reggie 'n' y'all


Here's another REA marine engine on eBay France. Looks superb to me and they really are fairly rare. Looks complete and a real practical runner. The seller doesn't say whether it's 5 or 10 cc. Looks like another "5" to me, and he'll ship to the US, and even Belgium!

I'm a REA fan. All the early REA sparkers are great runners, superb quality and robust. I've never been into marine engines... but I can feel myself weakening, we even got this one on the right thread!

Here we go Bill, finally got her on the bench. She's a shaker or so I thought. The after market drive washer I bought is not machined square . Not only was she shaking,it rubbed the timer housing. I installed the one that came with it that was cobbled up by someone along the line. The home made drive washer is a bit crude looking but actually works better.

I'm not a fan of using a starter on the old engines as you risk pushing the crankpin into the rear crank housing sometimes. However with the timer arm being so close to the prop plus the fact that she starts pretty fast,I'm sticking to it. It also does away with cut fingers due to forgetting to retard the timer or in this case switch the two speed timer and you can start her at full advance.

Cool videos of those engines there.
I can see where a plane wouldn't last very long with a shaker like that.

Maybe you should check everything over... I occasionally run a couple of Forster .99s, and I've never had any vibration problem, and for the last seventy-odd years, no-one has ever considered the .99 to be a shaker...
Are the spinner and prop properly balanced?
Do everything slowly and think about every single action before you actually move or touch anything.
The only problem I've had is that they sometimes start when I'm just pushing the prop to a convenient flicking position!

W....... K......


OK recently found this one. It is 5cc, and despite the looks, it does turn around and is complete so it will make another example of before-and-after-restoration on my website. In the next months that site will have quite a few engine pictures added. I think this is an easy one.
