Also, boost referenced power valves

Mid 11’s is what I will aim for. Planning on checking afr’s, and everything else on the garden hose, in the driveway, hoping for the middle of August. Still have a lot of parts to put on.

What do you think about running the carbs sideways? I read a thread where someone had 500 hours on a similar set up , with the carbs sideways. Also said they ran the jet two size’s larger over the number 7 piston.

Ok,,, scratch that idea, how about 2” carb spacers?

I was thinking carb spacers may help keep the intake air cooler, if that was dumb question, believe me, I will have more! LOL

Still wondering about the NGK #7 spark plugs. That is what came in the enigne’s from the previous owner. They were very black, almost fuzzy with soot. very rich at some point, then he detonated the port enigne, rebuilt it, let it sit four years, and sold it to me.

Thanks again for the help, just looking at the MegaSquirt, that’s more complex than the Daytona for me. If I use the Daytona in two D mode, would it be effective, or do I really need the map-2 bar sensor, and the pc mapping that 3 D will require? I’ve read up on the Daytona, wondering if my computer skills are to lacking to have it ready this year.( or next, Lol)

You’ll still see a lot of benefits even with the the standard table. Still have start retard, idle stabilization, rev limiter, and delayed start which lets the motor turn over a couple to reach full cranking speed before it send a signal to fire up.

I did find the Daytona kit, including, coil,and the map sensor wire, for under 1200 $ for two. I’m going to start there get the boat going, then try to figure out the computer part. Once it’s in, it may not seem so intimidating. I will let you all know as soon as I get everything installed, and start the initial tuning in the driveway. Again,THANK YOU! Everyone for your time and input!

It’s really not that difficult. The computer ties into the tach/brown wire. Upon install make sure that wire is accessible and they send weatherpak comnectors to add to make it easier. Follow install instructions. You can even download all the software right now and start playing with it. Don’t even need the box. You can set it all up at the kitchen table then take computer to the boat and upload to the boxes. The software downloads are available on the website.

The timing control feature’s sound very good. I have to admit, I’m going to be thrilled if I can make the first trip with no damage.

Hi again, sc here, I’m back! One new question, seems like an easy one, bought the Daytona sensor ingition’s and need to know for sure, do I lock out the distributor, and set it at 32’ or so, also do I need to refaze my msd pro Bullitt distributors? Been working like crazy to get it all together this year.

Thanks, I was pretty sure to lock it, just wanted to make sure,I was just installing my fuel pump block off plates, and found a factory merc. Fuel pump on the rt. Engine, left had a high performance after market, no worries, lol. Back with more updates soon, Stu

More updates, I was locking out the distributors the other day, remember I told you about the plug wires all zip tied together, well, when I was removing the the the msd’s7 al the distributor pick up wire was stuck, guess where. All zip tied in with the spark plug wires. Probably won’t reinstall the Daytona’s this way. I’m ready to set my rev limiter, can’t figure out the setting. Instructions say, use 06-99, wouldn’t that set it at almost 7000? Also, which canned timing curve would you recommend? Still hoping to get going this year, probably won’t have time to figure out custom mapping, MAP sensor, and the rest of it. On a exciting note, did get to go to clam diggers last night, in marks 40’ hawk( my old boat) great time for all. I got to be the designated driver on the way home. The lake was angry! Hell of a boat! We got wet.

Ok, I think I have the rev limiter figured out,got the boxes installed tonight. Only have 14 things left on my list, out of about 109 , so not to bad. New caps & rotors today, lost an hour and a half trying to fish the stainless distributor cap screw out of the bilge, then my neighbor told me I should have used the shop vac, oh well all is well here in Curtice Ohio, back with more updates soon, SC

Ok I’m here, wow! Got her going today! A couple of leaks, nothing bad. Check this out, got to thinking, a lot of people had luck with 32” locked timing, so I thought what the heck, returned my Daytona sensors marine cd1’s got my 1100$ back. Then , bought Delco hei chips, bolted them to my ingition mounts, (3/8”aluminum plate) wired them to my msd distributor’s, wala, instant ingition! Hit 72 on gps, never wot. Mabey 7/8” . 93oct from gas station. Seems tight, back soon with afr updates,,,,, sc

By the way, 80$ seems like a good deal instead of 1100$ just saying

[QUOTE]well, the motors are ok. Left tranny had water in it from a bad cooler. Rebuilt over the winter. Decided to go with the Daytona sensors, to much time and money to blow it all up. Will get back here soon Kith updates , again, thank you all! Especially MT,but not only. Been going to collage onOSO- lol ,,,,SC[/QUOT

I need to get oil temputures, looked at in the pan sensor, and on the filter block. Has anyone ever modified an oil plug to have a temperature gauge incorporated with the plug? Would make instillation much easier.
