There is an original OPS gearbench for it.

Netjes gebouwd Dirk, complimenten, waar heb je de tekening vandaan ? Groeten Rob.

No, I have only the one in front with the muffled pipes. The back one is from a friend and is for sale but expensive also never run. Difficult question if you want to run it, spare parts are not available as far as I know. What type of boat do you have in mind, a Cobra from Merlotti ? Rob.

Also unable to upload the link of the B 20 directly. Group OPS: Facebook Groups > media > video's (might be neccessary to register) Hope this works ? B-20 with muffled pipes is mine. Rob.

In the OPS Facebook group there is a film when you can see and HEAR the B 20 running. File is to big to attach.

I think te conrod is not right in position. Looking from this side you have to see the lubrication hole of the conrod. Also the countersank side of the bronze bearing must be faced towards the crank because of the radius of the crankpin.

Chris, If you need any parts from OPS, they are available from Mantua in Italy. Rob.

Brad, For OPS engines contact Massimo Poldi at Mantua in Italy. www.mantuamodelshop.com Rob.

Shane, PM send. Regards Rob.

Hi Marc, I think that ABC 2116-3 or 2118-3 or a modded Octura 460-3 are the best 3 blade props. Your boat runs more stable on choppy water with a 3 blade but a 2 blade is absolutly faster. Rob.
