The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Sorry for the necro lol but it was appropriate :)
Thanks to this thread and another on iBoats, I installed the carb from the Force 50 to my Force 40 today. Everything worked great! Picked up 4mph and +200rpm, running what seems to be 5800rpm, a little higher than it should be. I'm running a 15...
I tried the carb-only change and it didn't work, motor just didn't run right. I suspected the carb body was actually different (TC131A on the 40hp, TC134A on the 50hp).
I found someone selling the TC134A on ebay for $90. Got it in, rebuilt it with a combination of two rebuild kits on Amazon...
