Remove your throttle linkage so you can do it all from the engine area, Pre set your light to what you want 32 - 34 rev it up get it done as fast as possible. Tighten up the distributor and re check, check idle and note for future.
My arms don't look long enough to change mine, did you remove the fuel filter/pump for access? Where are you located?> |
Advance means before zero
|
I was able to do it with the fuel filter there. Taking the pulley off made a decent amount of room but it’s still pretty tight in there. I did take off the top bar and the sliding doors under the hatch so I could lay down. I’m 6’4” so that doesn’t help. All in all I think it took me about 3 hours but I’ve never done it before |
Gary summed it up pretty well. I ran a v8-24 but it popped out. I run a v8-22 now because I have it. Would prefer a v8-24 or v8hp. But set your base timing as Gary suggests. I run 33° all in just to be safe. Detonation is not a good thing and anything over 34 your at risk.

Welcome back Hunter

Oh and glenamy I’m located in mass on cape cod |
Another update. Took the boat out today. Went down an inlet that has a fast zone. Didn’t want to go too far on the first run. Went well. Made it home. Lol. Have to do plugs and wires and fine tune timing. Had a hard time getting on plane and couldn’t get rpms over 2800 but temp and oil pressure were great. Had a hard time seeing the timing mark but thought I had it at 10 but all in all had a great first trip!!!!! My wife and I went up and down the river for a couple hours. 45 minutes each way out to the ocean. Plugs and wires this week and find a better timing light for the final tune |
Mark the proper timing marks with a white paint pen to make it easy.
|
All I had today was red and it’s too dark. But all in all a good day |
Do yourself a favor and flush the engine for atleast 10 minutes with fresh water after every single trip. You will destroy that engine leaving salt in it.
|
I did. Been out of boating for years but I did flush it. I did that with my last boat too thank you for the advice!!!!! You guys are great and very helpful

2800 rpm? seems more than prop. Did you (engine NOT running) remove flame arrestor, full throttle, and check for the secondary's are wide open?
What did you set as "all in" timing? |
Sounds retarded. They have a nice timing light at Carquest with a tach on the screen so you can do it all from the back. Great to hear that you got it off the trailer. Like Glenamy said look for secondaries to open and for a squirt. Rear bowl may be empty. |
For sure get a light with the digital delay setting and a tach.
|
Hi guys. I believe it’s a 21 pitch mirage. Last numbers are 21. I’m going to put new plugs and fuel filter in hopefully tomorrow and the time it. This tome when I timed it I only had a non advance timing light and the mark was hard to see. Going to paint the mark white as suggested and use a better light. I’m sure it’s probably a timing thing. I’m also gonna by to check the secondaries to make sure they are opened up fully too. I will let you guys know what I find and as always thank you |
So today I re timed the engine. It’s definitely at 10 degrees at idle now. I’m pretty sure it was way off before now that I could easily see the timing mark this time. Put new plugs and fuel filter in. Couldn’t get a set of wires. Checked the secondaries and they are open all the way. Still couldn’t get my hands on an Advance timing light but it’s running good. Have to put in the water again and test it. But hopefully I can get my hands on another timing light to set advance timing. Trying to get it ready for a decent length trip on Saturday. |
So I took the boat out this afternoon and wow what a difference. Revved right up. Got right up on plane. Speedo doesn’t work but putting a chart plotter on tomorrow morning before a day trip so will update with gps speed. Thanks everyone for all the help and advice!!!!!!!! Glad the work paid off and got it going good. Couldn’t have done it without all the great advice on this forum!!!!!! Thanks again!!!! |
On a good day she should break 50 mph. Have fun
|
Thanks O’Connor. It was rough on Saturday so didn’t get to open it up but seems like I’m only getting about 3500 rpms. I believe the prop is a 21 pitch mirage. I was only able to base time the engine as I couldn’t get an advance timing light. I also changed the ignition module from a v8-24 to a v8-22 as that was all I could find at the moment. I’m sure that’s all playing into it and will keep trying. It’s getting better each trip |
If you have a v8 22 you need to be at 11-12 base for a total of 33-34 all in.
|
I think that 330 hp calls for 32* total and max 4,200 - 4,800 rpm. With a 21 prop I would think even being tired it should pull 4,200 rpm.
What gps speed did you get? Keep at it you will get there. |
Would 1 or 2 degrees make a difference of 1000 rpms? |
I didn’t really get much of a chance to open it up. It was pretty rough. Hit 30 mph on gps but only for a few seconds. Conditions were less than ideal. Lol. Also. How much is an acceptable amount of water in the bilge? Seemed to be a bit maybe 5 gallons when I pulled the plug. There was a bit of splash over on the trip so that could have accounted for some of it. I haven’t checked the bellows which I will this week. I would think it should stay pretty dry for the most part. If bellows check out is there anything else I should be looking at? When it’s running the cooling system isn’t leaking so that’s all good |
I have plenty of weekends where I pull the plug and nothing at all comes out. Some it's just a quart or so from people and the kids on and off a dozen times a day. You shouldn't be getting much if any. Bellows obviously, then any hoses. Also are you putting teflon tape on your drain plug? I found mine needed it to fully seal without having to tighten it to the point I felt it was over tightened.
|
I did wonder about Teflon tape. I haven’t put any on but will try that next time to see if that makes a difference. I would like to see no water in the bilge. |
Also check your speedometer hose. They are prone to deteriorate over the years.
|
Ok. I will definitely check that too. Seeing as the speedo doesn’t work. Maybe that’s it. Stupid question. Where is that located on the transom end? |
5 gallons is a problem that you need to address. I had a corroded transom assembly that leaked in a way that was hard to diagnose until I had replaced every other possibility. Poke around the sides of the bellows hub with a screw driver to detect soft spots. Saltwater boats of this age are proned to TA failures. At the very least an auto pump switch is a good bet. Don’t sink my sister ship! LOL. |
Another update. Went out yesterday and the seas were calm so hammered the throttle and only got 3400rpms and maxed out about 38mph. Cruises nice at 3000rpm and around 30 mph. I’m thinking it’s the timing but still have to find an advance timing light. Ran good. No coughing or sputtering. I did find out that the fuel gauge is not accurate. Had to get the tow of shame back to the harbor. Ran out of gas about 3 miles away from the dock and gauge still read 1/4 tank. At least now I know all old gas is out and gauge is off. Lol. Probably the sender. All in all great day on the water!!!!! |
So how much water in the bilge? Did you find the source of the leak?
3400 rpm max, if timing it's a lot more than a degree or two. |
There was water in the bilge. Can’t tell where it’s coming from. Only seemed like about a gallon but I really want to find where it’s coming from. Season will be winding down here shortly so I think I’ll pull the drive and see what I can find. Bellows seemed good but I want to replace them and all hoses as I don’t know how old they are. I put Teflon tape on the plug this last trip so that wasn’t it. I know sometimes it can be hard to find. Could it be anything behind the swim platform? Anything behind there besides exhaust to look for? |
What I would determine first if I were troubleshooting this.
Do you get water while it is just sitting at the dock Does it leak water while sitting at the dock with engine running Or does it leak only while underway? |
That’s one of my problems. The dock I launch from is always crazy busy so can’t sit there long. Kind of have to get in and get out. Hopefully with season winding down I can put it in and leave it at the dock for a bit so I can do those tests. I figure if I can sit at the dock for about a half hour could let it sit for 15 minutes without running then 15 with it running to see if that shows anything |
When i launched my 242ss this spring, I first started it up at the launch, water was in the bilge. So i would shut it off and look for where it was coming from. nothing.
Started back up and immediately started filling back up with water...come to find out, my Raw water pump hose was off...and the location is wonderful on these boats....under the engine. Very hard to see, so i had to lay on the engine (after it cooled down), and hugged the motor to find the hose and reattach it. if you're leaking from this hose, it would almost be impossible to see from up top |

Now you know where to start looking closer. |
How much does the rpm change after trimming up? Are the trim tabs up as well? Is the flame arestor clean? It still sounds like the timing is retarded. |
Hi ph1971. The trim tabs are up. I did mess around with trim to see if it changed but best result was when they were up. Spark arrest or is also clean. I need to get my hands on an advance timing light because I also believe it’s going to be the timing. The motor itself is running great just not getting all the rpms out of it. Hopefully will have an answer soon |
If you think your timing is that far off to affect your performance that much I wouldn't be running it until you checked it. You can cause a lot of damage($$$) with to much timing as well as to little timing. You can damage the valves, seats and guides with to little timing. You are creating a lot of heat in the exhaust port and manifold and the fuel did not have enough time to burn in the cylinder.
|
So yesterday I replaced the ignition module back to the original v8-24. Put a new set of wires and bought an advance timing light. When I went to time the engine the mark was bouncing all over the place so couldn’t set the timing. Didn’t have this problem with the last timing light I used. Was hoping to go for a good run to see if I could get the rpms up. Guess there’s always next year |
