I have a new 67 Red head in my twincraft deep V which has only two tanks of fuel run thru it so it is not even broken in yet. We have decided to retire this boat & swing over to gas. Would you or anybody else be interested in purchasing this engine or the whole boat?

Piston & Sleeve on new OPS red head are very different from old Gold Head 67 There are extra porting slots. Rod length is the same but the newer red head came with a better rod in that the rod has oil holes on both ends for better lubrication.

Thanks for the fast reply.

Who is the importer of Pico engines now? Does the importer sell direct or thru dealers & if dealers - which ones. Any web sites or phone Numbers? Thanks for a reply hhn

I have raced with OPS engines for over 30 years & will stack it up against an equal displacement CMB anytime. One suggestion - put a OS MAX 9B Carb on it fore better response & easier tuning.

I have one that is practically brand new in a hand made & beautifully finished wooden box. If you are interested in it please e-mail me @ [email protected]

Set it as rich as possible & yet keep running. Run a few tankfuls very rich. Then start leanng up a litle at a time. Do not try to do this in one day. Let engine cool down after each rich run. This way you will seat bearings properly & not scortch the hell out of the piston & sleeve. Once...

We run this engine in NAMBA District I We have an OS 4D Carb on it with a Kalistrative Remote Needle. The reason for the remote needle is just spacing in a very small area. You could just as well use the OS 3rd Channel assembly. We are using a Cooper silent pipe and 65% Nitro. Keep the head...

Go to Tower Hobbies.com Scroll to their parts store then select OS Parts - then select OS 9B Carbs (Keep Scrolling - it is toward bottom of list.) You will find the inlet nipple with gasket & all other parts for this carb.

Once you find your best carb needle setting on a given day you then use this flow meter to get a reading on that setting. As an example. Let us say that you get a reading of 376 on the meter from this good run.. That becomes your base. The next time you go to the pond to run your boat - let us...

It came with brass flywheel. I put an OS Max 7B carb on it with remote 3rd channel needle & it ran beautifully. 7B Carbs are not made anymore but Tower still sells a 9B which can be madea to fit. Carb is a little pricey but if you put an OPS 67 piston & sleeve in it you will be highly...

It is the original OPS 65 with a built in water cooling jacket, I ran them for over 20 years. All current OPS 67 parts will still fit this case. I wish I still had this case. They were bullet proof & the cooling was great.

Thanks - got it
