Help Noob Determine Interceptor Engine Size

Sounds like you might be new at this, so a couple other tips as you get it water-ready.

When you run it in the driveway, do not run it dry. Be sure to give it a water supply. This is most easily accomplished by removing the water intake hose from the thru-hull fitting by the transmission, sticking a garden hose into it and clamping the intake hose to the garden hose. If you have been running it dry, there is a chance that you cooked your water pump impeller. If you did run it dry, let us know and we will walk you through that check and fix. Also, once you have it running on the hose, do not put the boat in gear. You will fry the rubber bearing in the strut.

As far as it not loving to start and run when cold, your tune up should address that. A little gas isnt unusual to get these old ones started. They all have their unique sweet spot. Mine likes two pumps of the throttle then a little throttle to turn the key. Usually starts right up with that. Once started, it may sound a little rough, although it should run at absolute idle, with no throttle. It may until it warms up and the choke opens all the way. Normal.

Thank you so much.   

So, I now see the info I needed was right there all along but that I didn't know that engine displacement and engine size are the same thing. I googled what engine displacement is and see it's commonly specified in (mainly in North America) cubic inches    I feel a little dumb not knowing simply things you all take for granted so thanks for helping me out.

I'm just going to replace the spark plugs and wires as well as the distributor and points for now as well as change the oil of course. Everyone tells me it's not that hard to do those things and my neighbor is engine savvy and ready to help. Not really sure if there's anything else I should be thinking about doing to it, but as long as it's running good, can I assume it doesn't need anything?

So far, the only thing noticeable about this engine is that it doesn't start too easily. I have to engage the throttle a little to get it going then ride a fine line of keeping the throttle in the right spot while it warms up or else it'll stall. Once it's warmed up, it starts right up no problem.

I'd say it's a 289

Hello, I'm a noob about engines and was given a 1968 Correct Craft with a 165hp Interceptor engine in it from my uncle. I'm trying to determine what size engine it is as I was told at the parts store they need that info to hook me with the correct parts.

The model is 165RS
The Spec says 104
The owners manual is here even though I can't find it anywhere inside: https://www.correctcraftfan.com/Downloads/1968_interceptor.pdf

Any help would be greatly appreciated as it needs a tune-up before it goes in this year and it's getting warm already! Thanks
