Hi Guys,

Need a bit of help, this is my first post here so hello and sorry if i'm in the wrong section or anything like that.

I have a 1996 wellcraft 21 excel cuddy powered with a volvo 4.3GL PNCS engine number 4110136898

I am getting a bit confused about what horse power i have and what timing i should set the ignition to.

The dealer i bought the boat from tells me it is 190hp and checking the wellcraft site it says this model had 190hp but the manual i have says a 1996 model engine is only 170hp the engine has vortex on the rockers, i have read that some of the early vortex engines can have vortex on the heads but not be a true vortex engine. i am guessing i have a poor manual which make me a bit worried about using the setting from it to set the timing.

I have the shunt tool and instructions on how to use it it connect to +feed after engine is started.

I have read some great posts here and used many tips and hope someone can help with my questions.
I am in Scotland so i run 95 ron gas.

Thanks for any help you can give Kenny

Hi Don,
Thanks for your quick reply and the link.
The oil pan is aluminum. the manual i have is an aftermarket one i bought on line so probably not that good.

cheers Kenny

Here is a link to the OEM manuals for your NC model engine and drive. You won't need the EFI or Ford manual, but download the others.

If you look at the Fuel/Ignition manual, there are tuneup specs with what you should be setting your timing at. I could probably tell you what the timing should be, but I would bet you learn more by looking for it.

There is also a change in what the manual says about changing timing, have a look at this link.

Thanks Don, a great help.
I had found the thread about the update on using the shunt tool.
