I am wanting to change the jets out on my 1993 Johnson fast strike 150. But when I looked the part up in the diagram, there are 3-4 diff jets in the parts list for each jet. Which ones are for my outboard?

Explain.-----What is your motor doing / not doing ?----What elevation are you running at ?-----Which jets do you want to change and why ?----The 150 and 175 hp jets are listed together.

Well I removed my vro pump and replaced it with a new double piggyback style fuel pump. Took it out, ran like crap. Came back and noticed all six of my float bowls were cracked in the same place. So I replaced my float bowls with new ones. But being a rookie I didn't do my homework before hand. I did not know that there was a high speed jet behind the drain plug on the float bowl that needed to be removed from the old and installed on the new float bowls. And I threw all the old bowls away before I learned of the jets. So now I need new jets to put in my new bowls and figured I'd replace all of them while I had em off. Just don't know which ones to order

my model number is j150glecg im pretty sure. Refering to my vro problems, well i had rebuilt it one time already. then the oil pumping part quit working. So i just decided to swap it out with one of the doubled up traditional fuel pumps. I can not get this thing to run right to save my life. Idk if its not pumping correctly or what, but i can tell my motor is starving for fuel. ive rebuilt the carbs, Im a machinist by trade so i made the jets i needed. I just pulled one of my factory jets out and built 3 replicas. The jet i pulled out was a 69D. After i made the replicas, i was looking at a parts diagram, and according to every diagram ive looked at, my carbs dont take a 69d. according to my research, a 1998 150hp fast strike should take a 70D or a 71D. Can someone please verify this for me. The jet im talking bout is the one that goes behind the drain plug on the float bowl. Also, Im a little bit confused about the pulse limiter. Im not sure whether im supposed to remove the pulse limiter or attach my vacuum line to it? one last thing, sometimes when my motor dies, you can hear the diaphram make a big wheezing noise as the motor dies. Ive never heard any other outboard make this noise before. i just feel like something is not setup right with this new pump. any ideas?

I am in Louisiana, so Im pretty much at sea level. and its not that i want to replace my jets, but i have to because i unknowingly threw the old ones away. i didnt know there was a jet behind the drain plug.

The pulse limiter is a " FLOWFUSE " for the VRO pump housings.-----Not needed for other style pumps.----I see a 57D or 59D for the 150 model.

Race one, idk where you got that part number from. I have
the fastrike should be a 69D, no?
A 69D is what I pulled out of mine. That's what I'm gonna go back if I can find 6 new ones somewhere

Worse comes to worse, see if you can buy used carbs, and transfer the jets over. There must be some junk motors like yours by now.

When I looked they were in the 50's for the 150 and in the 60's for the 175.

It was confusing so I shut my mouth.

Racerone so you're saying I should remove the pulse limiter and what just put a nipple in the hole and attach my vacuum hose to that nipple???
yes. use a 1/8npt to 5/16 barb fitting with gel seal around the threads. double check its not a 3/8 pulse fitting but i think 8mm/5/16 is correct

i think the fastrike 150 is basically a stock non-fastrike 175. honestly i could never tell much of a difference between any of them, accept for the 1st year 1991 un-molested ones with the hot heads. those were special.
