    Skiing behind Scarab Jet Boat

    Probably should be known that we aren’t talking about a scarab of the traditionally known type, I’d be sure. If I’m right, it’s one of the seadoo mass produced things, that someone threw scarab branding on. Powered by twin seadoo 3 cylinder jet ski engines. I’m not sure how they would get on...

    First boat - 60hp Bigfoot - trim won't stay up during above no wake operation - what is normal?

    Kind of depends how high the engine is. If you mean way up beyond the normal trim range and into trailer range…some engines won’t allow beyond a certain rpm. But with this era of engine and the description or mention of the engine lowering itself under load, I’d have a confident notion that...

    engine just quits

    Hi. Have you checked the health of the rectified electrical system these have ? If you still have that system at all. Perhaps you have upgraded her (like most folks tend to), with the more reliable alternator modification kit.

    Have you removed and taken the whole vst off the engine ?

    Outfitting Klamath 18 CC with 2017 60HP CT trying to figure where to start on Prop size. Probably aluminum.

    Merry Xmas to you too. You know, and maybe I know…but not exclusively and for sure…you’re dead right in the thinking that I also have… As prop pitch increases…traditional thinking might suggest that diameter reduces a little. So I was just surprised to read of a 13.anything by 16” pitch, in...

    Outfitting Klamath 18 CC with 2017 60HP CT trying to figure where to start on Prop size. Probably aluminum.

    It is. Up to 115hp these days. Just thought that a 13x16 would be an odd size for it. There is certainly a 16x16 that would fit it

    Outfitting Klamath 18 CC with 2017 60HP CT trying to figure where to start on Prop size. Probably aluminum.

    Remember it’s a CT gearbox. If it’s anything like the other CT 2.1l mercs (like my 115 version), you’ll need the larger (and better range) type props, for the larger gearbox size. I run a 19” or 20” 3 blade tempest plus or enertia on my 19ft cuddy and 115 ct. 43-45 mph at 6100/6000 rpm roughly

    Engine Overspeed?

    What were the details of the mapping, if you might know. Would love to know who can do that. How did they map that ecu to have the fuelling suited to those rpm ? I thought it was only pro charger or whipple or someone like that, who could manage an adjustment to the fuelling on these. Perhaps...

    your opinion

    Fair point. Not something I’m familiar with or even a common thing over here. Can only dream of such a thing ! Just presumed the guy was doing what he could with what he had currently. Over here fuel consumption versus power gain is a big deal I suppose. Along with not readily available parts...

    your opinion

    I presumed he was using the block he had and rebuilding ? Not starting from scratch. The former being the case, it’s going to cost more than $25 different. There will be the matter of the actual “stroking” to account for, at the least.

    SPARK PLUG CROSS THREAD

    Needs heli coiled…and properly done too. Or ideally a replacement hood used cylinder head instead

    your opinion

    Is she a Larson cabin cruiser or similar ? Or perhaps a smaller open bowrider? Either way…I’m maybe thinking or wondering if there would be any point in going down the stroker or power crazy road. Would the financial outlay and extra thirst be worth it on a cruiser ? Or would it be handled by a...

    Excellent. Glad she’s sorted. Just mind and be careful with jumping things. These can be sensitive bloody things. Anyway…nice one and all the best.

    Did you get a look at the plugs that were bad ? That can tell you a story or two.

    Duel battery troubleshooting

    Sounds like you might have cross wired your batteries in series, to give 24v. As a result and after connecting things correctly, one of your batteries might have suffered ? That said, I and many others have done just this very thing deliberately, to give some extra juice when required in an...

    Manifolds (Trying to figure out what I am looking at)

    Hi. Is that an engine from a truck or car ? Is it possible that you’re taking water in, as a result of a not suitable cam behaviour?

    What model is my boat.?

    No probs. Yeah. It’s a sun bridge. Great wee boats for getting a genuine 4 berths for cheap and a small hull that’s easily managed. Windows were known for leaking and making a mess of the roof lining. I had the 2255. Loved it. She had a 4.3 in her. Keep an eye on that omc out drive I’d say. If...

    What model is my boat.?

    I know what she is. She’s a bayliner 2155 cierra model. Most had a v8 omc originally. They were made in the latter part of the 80’s. Usually like 87/88 would be the most of them. They were replaced by the later 2255 model. These had a bathing platform added and a change of power plant towards...

    Prop sugestions tohotsu 2023 BFT 150 D

    Sounds sensible to me. If you do decide to take a gamble on a pitch for a stainless to try out…good news is that you are in the commonly used and sought after pitch range. So basically, if you see a bargain, used and great condition stainless like a laser 2 or similar (always know where you are...
