Please help with my 1989 320 EFI Mercruiser
 

Very frustrated. It appears that the throttle position sensor, Merc. PN 14882A2 went bad. They are no longer available from Merc. Has anyone found a replacement from a secondary source? Any ideas? Maybe someone replaced theirs with an intake and carb set up and could sell me some of the old parts? Thanks.

There is a # printed on it, but I cannot see it from the below picture from Merc's catalog.

Can you get the # off the TPS and we can try to go from there ?

That is a link to BAM marine's website. I called them yesterday. No luck. Thanks.

Couldn't make out that number on the bad one. Will pull the good one off the other engine later and see if I can read it.

Can't believe I may have to switch to carbs over 1 stinking sensor.:picard1:

last time I seen one of these on the shelf, cost was about 260 to 300 bucks - Possible a dealer might have old stock still sitting on the Shelf, one or 2 maybe somewhere, but I bet the price would be the same if not higher being in a Merc package - thru a Merc dealer.

Looks very Lucasish,

Are you able to sweep the sensor to find the resistance range?


Jeff

Thanks for the help. There is one of those on eBay now also. The end that goes into the throttle shaft looks different though. I don't know how to sweep the sensor but think I can figure out how to throw this crap fuel injection in the dumpster LOL

Just hung up with them to verify availability. Not in stock. Cannot get. Thanks anyway.

What about an Edelbrock dual plane air gap intake with a Proform or Holley 650 double pumper with 4 corner adjustments and no choke?

Found a ton that look like that one too, but shaft is all wrong. Jaguar, Rover, etc,etc.

I gave up looking at 100's of pics and am waiting for the # on the TPS itself. This will be the best way.

Well I bailed today. Ordered carbs and intakes from Summit. Thanks to everyone who came to my assistance in this thread. If anyone needs parts the setups are for sale in the swap shop.

Give me the # to the tps anyway.

Here ya go SB. If you need a high rez pic pm me your email.

What happened?

Ya there was another thread with this also. Looking forward to hearing outcome. Any gains? Loss? Wazzup?

Ready to go. Just haven't had the time to try her out yet. :(

Finally got her out for a ride today. 21 inch mirage props spinning 5400 with a conservative trim. I am very pleased. Good to be back on the water after 4 years off.

5000 max with the fuel injection

Great news glad to hear. How is throttle response?

Also what did you do to convert. Carbs.dezcription? Intakes? Other parts?
Thank you
