Lund angler ss top speed w/ johnson 140 4 stroke ss/pro...

[the goon]

Just picked up a lund angler ss w/140 4 stroke johnson my top speed is 46/48mph rpm 6100 do you think I am propped right. I think the prop pitch is 19 or 21 not sure cant find a number on the prop

goon,
The speed sounds about right. I'm kinda curious which pitch prop you actually have, 19 or 20? And is the prop aluminum or SS? The reason I ask is that my father has a 1800 Explorer w/ a 140 Johnson & 9.9 kicker and with a 21 pitch factory 3-blade aluminum; motor mounted in the 3rd hole from the top and it comes up a little short in the RPM category. Top speed is around 42 mph @ 5400 rpms(dash tach). Given this info it sound likes you've got it about right. Max rpm on the motor is 6200.

I have that engine on a Triton 18' center console fiberglass boat and have the 14" x 20" stainless prop that Suzuki supplies Johnson. Runs 46 at 6200 RPM. Could probably get more speed with 22" but I don't want to sacrifice low end. Your numbers seem right. I tried one of the 3rd party 21" props but it didn't perform as well as the OEM prop. Make sure you are running a 14" dia. The engine is geared down in order to handle the larger diameter prop. Supposedly, less slippage. The engine is great.
