Couple of questions-

56 mph, it that on gps?

What carb is that? Does it have vacuum secondaries? Are they working?

Where is the timing set? Initial should be a minimum of 10 degrees, up to 14 or so. (Also depending on the degrees of mechanical advance)

How fresh is the gas?

Is the tach accurate?

It sounds like the boat is running pretty well, and the tach might just be reading incorrectly, if boat speed is accurate.

That's all I got for now.

Itís has a Holley 750 with manual secondaries. 56 was on gps. I drained the tank completely, put fresh gas and a can of sea foam in each tank before I took it out for the first time. I will check timing. The guy I bought the boat from said he had it at 65 on gps, he could of been yanking my chain.

Engine Mechanical / Electrical / BBC rpm fix
« on: June 20, 2019, 06:37:27 PM »
Hello, so from what Iíve been reading my boat is supposed to rev at least to 4600 rpm. I have a 1992 carrera eclipse 20.5 with a 454 bbc with about 136 hours total. I do not know if itís been rebuilt or freshened up as I just purchased it. Motor runs solid and feels and sounds strong. Has a MSD ignition and a whole bunch of little goodies. I have an American turbine pump built by Tom Papp. Iím not sure what impeller is in it. When I go out I can only get about 4K rpm out of it at 56 mph. What should I start doing or looking for to get it to perform at what itís supposed to? What should I check? Thanks in advance for the help.

On my 454, with logs and snails, I run it at 130 - 140. In no wake zones, it climbs to 155ish.

With open headers, 120 is enough.

Remember, it is a single pass system, lake temp plus 50 degrees is sufficient for open headers.

Logs and snails preheat the water before it goes to the engine. Always keep the temp below 160, where the hard water starts depositing contamination on the inside of the engine.

Just my $0.02

Ok I will adjust accordingly, thanks for the help

All boats are different.  I have a 76 Rogers SC with a BBC in it and as long as I don't come off plane too fast it doesn't take on water.  However, if I get around wake boats it tends to take on a little.  I have gotten it over the side while making a tight turn to the left with my fatass on that side.

I've only been in a jet for the last two summers, my suggestion is to go out by yourself or with a buddy and play with the boat.  Learn it, see how it handles different water and wave conditions.

I went out a half dozen times before I ever took the kids with me, learned a lot about my boat and how she handles, I'm still learning, but at least I have a decent grasp before putting others in possible harms way.

Ya driving is fine I was just wondering about when your floating down river and thereís a lot of traffic around you. Didnt know if the boat will get chop crashing over the sides or if it just goes with the flow. I have two 750 gph bilge pumps on her. But I will definitely take it out a couple times before I start taking people out with me. Thanks for the help

I have a indmar 454 with their log headers. I just bought this boat and keep in mind itís my first boat Iíve purchased.like an idiot I messed with the valve that controls water flow to my engine not knowing what it was. So I took the boat out for the first time and I opened the valve 2 1/2 turns open. I let the boat idle on the trailer for about 5 minutes and the temp gauge didnít move at all. I closed it to 2 turns open and took the boat out.just idling around my boat got to about 110. WOT the temp was just registering at 100 which is the lowest my temp gauge goes. After I came back from a run I could hold my hand on the header. It was hot but not unbearable to wear I had to pull my hand off of it. My question is should I keep restricting water flow until my boat actually starts registering about 130-140 at idle?

Hello Iím new to the board. I just picked up a 1992 carrera eclipse. I have grown up boating all my life but have never been in a jet boat. I have a really stupid question. I took out my boat for the first time and while floating around I was deadly scared that any little wake will roll in to my boat and sink it. So my question is how well does a low jet boat take mild chop stationary? Do I really have to worry about anything? I have a 6 month old daughter on the boat and do not want anything to happen so Iím overly cautious. Thanks
