    New Crusader Owner needs help with engine tuning/timing

    When I changed the oil a couple weeks back, the oil I extracted did not look like it had water in it. Weather is bad here so no work this weekend on the motor. I did find some used stainless MerCruiser risers on Ebay. One titled " Mercruiser 816900A5 816900-c 4” stainless steel exhaust riser...

    New Crusader Owner needs help with engine tuning/timing

    thanks Makomark. Which dipstick? I'll pull plugs this weekend. Am I looking for corrosion? Elbows are easy access. I can pull those and inspect the interface to the manifolds also. I saw some options for stainless exhaust elbows. If only a couple of hundred $ difference, maybe that's worth it to...

    New Crusader Owner needs help with engine tuning/timing

    The manual has 2 pictures for fresh water flow. One is "with Risers" and one "without Risers". The only difference is an approximate 4 or 5" piece between the manifold and exhaust elbow. My engine does not have this "riser". I had thought the elbow portion was called the "riser"... I don't have...

    New Crusader Owner needs help with engine tuning/timing

    The manual is Crusader Owner's Operation and Maintenance Manual. Appears to be the original. It says 2004 300HP Carbureted 350.

    New Crusader Owner needs help with engine tuning/timing

    Model: CXLAVRL152D Serial: 640608 Manual (document number in footer): L510019-04 I haven't pulled spark plugs. That's going to be fun! But I guess I'll get that done. I won't be running over idle going forward. Thanks for the info. I didn't like the feel anyway.

    New Crusader Owner needs help with engine tuning/timing

    Hi everyone, I've been a member here for years but spent most of my time over on Evinrude or Yamaha outboard forums. I've owned a Shamrock years ago, the 17' baby Shamrock with Mitsubishi inline 4, and now I own a Chevy 350. A few months back, while searching for a repower Yamaha for my Bay...

    1993 Mariner (Marathon) 25hp 2 stroke - Tiller conversion

    I picked up the motor a few months back and it was originally set up for remote control. I'd like to convert it to a tiller. I have been collecting some parts (probably some wrong) and have learned along the way that there are (at least) 2 options. By the attached photo, can someone tell me if I...

    2003 150 hpdi (Z150TXRB) trim tilt and starter issue.

    First time poster to the Yamaha forum, I usually live over in the Evinrude/Johnson forum for some old antiques I have. But I also have and love my old Yamaha 150 hpdi. Been a great motor for a long time. This issue happened a few months back and I'm just getting around to fixing it. So what...

    Struggling with a spark test (1956 Johnson 10)

    I have been trying to get a spark to jump 5/16" to 3/8" gap with a tester I got from an automotive store. It's not working yet, and I've traced down all items I can think of. I may be doing something wrong. So here is my procedure: 1. remove both spark plugs. 2. Gap tester to desired gap. I've...

    19556 Johnson 10 (QD-17) tune up question

    The last few times I've run the motor it has been a little less than perfect. I wanted to give her a good tune up. I expected I would be cleaning the carb and checking the ignition. I tested the ignition with a spark tester, expecting to see the spark jump 3/8". Test showed it would jump 1/4"...

    1957 Evinrude Big Twin. A couple of questions.

    So I ran across a nice Big Twin, model 25028, and comparing to the smaller ones of the same year, I have found some differences that I'd like to learn more about. 1. What is the purpose of the Cut out switch and how does it operate? 2. What is the purpose of the mercury switch and is it...

    1972 Johnson 20HP - What exactly do I have?

    I posted a few weeks back about a Johnson 20 I picked up, model 20R72R (1972). I haven't spent much time on it yet, but have noticed a few unusual things. My first post was just wondering if the 20 and 25 hp were close enough cousins that I could upgrade it easily. Quickly found out the blocks...

    1972 20HP and 25HP Johnson models

    I ran across a nice freshwater Johnson, 20 HP, 1972, model 20R72R. It appears to me that Johnson had a 20 and 25 HP model that year and Evinrude only sold the 25. From the parts list book I picked up from Ebay, I can't find the difference between the 20 and 25HP Johnson models. Can anyone tell...
