    Rochester 2 jet running rich before and after rebuild

    Is there an overflow hose from the fuel pump to the carb? If the fuel pump diaphragm is leaking, it could be pumping extra fuel to the carb and raising the bowl fuel level, mimicking a float set too high or overflowing the carb

    Nauticus Smart Tabs on 97 Interceptor 212

    Hi folks. Just wanted to share my experience. I recently acquired a 97 Caravelle Interceptor 212 with a Volvo 5.7 GS SX drive. It's a fast, fun boat and I got a good deal on it as it needed an engine replaced. It came with a wake tower which was great for us as we like to do wakeboarding...

    Penta 270 Outdrive U-Joint Options

    I have used automotive U-joints in a sterndrive with no problems. I can't see any reason why they won't work as long as they are the correct size. If possible, remove the old U-joints and take them to the parts store and verify they are the same.

    Truck cam with captain's choice?

    Checked the timing. 10 degrees initial advance. 32 total at about 3000rpm. I'm gonna leave it there

    Truck cam with captain's choice?

    I do need to put the light on it and check current base and full advance timing. The two times on the lake were definitely not apples to apples since the weight in the boat was a lot more the second time. But we did get improvement in rpm and speed by advancing the timing a little. Probably...

    Truck cam with captain's choice?

    Sticker on engine says 8 degrees initial timing. I started at 6 to be safe and advanced it just a little by feel. Haven't put a timing light on it since then. I'll see where it's at and might try a little more but probably won't go above 10. I also didn't check total timing but it was advancing...

    Truck cam with captain's choice?

    Hey, so just to follow up. It's been installed and running for a while now. Runs great, no problems. Been on the lake a couple times. First time was just me and bare minimum of gear and whatever little gas was left in the tank from 2 years ago. Started with very conservative base ignition...

    Truck cam with captain's choice?

    Yes lobe separation is 109 degrees but it was the cam in the engine already and commonly used in marine engines. I ran the numbers on a cam program and there is no valve overlap. If the duration was longer there would be which is why larger marine cams have more lobe separation

    Truck cam with captain's choice?

    Well I got the cracked block engine torn down and found out it was a rebuild. Pistons are 30 over. But it had a roller cam that judging from its size and the numbers stamped on it is the equivalent of a GM 395 cam which seems to be pretty standard for marine cams. A bit more lift and duration...

    Truck cam with captain's choice?

    Thanks Bondo. That's what I suspected. I ran the numbers on the truck cam and it didn't appear to have any valve overlap that would cause reversion problems. I just wasn't sure with the captain's choice exhaust if there would be any issues.

    Truck cam with captain's choice?

    Hi all, I just acquired a new project. It's a '97 21 foot bowrider with a Volvo 5.7GS with a cracked block. It does not have vortec heads, and though I just pulled the engine out today, I haven't had a chance to see if it's a roller or flat tappet cam. As a donor, I have a 5.7 from a 1998...

    1987 Cobra 4.3 won't rev

    Hi all, first post here. I have acquired a project boat. It's an '87 Seaswirl with a 4.3 Cobra. The engine was blown and I replaced it with one from a Chevy pickup. Good compression on all cylinders, ran great, was actually a rebuilt engine and in really good shape. After installing, it...
