Still waiting to test the fuel pressure regulator. I did get a turn key quote for a rebuilt powerhead $8,700 with 1 yr warranty. My tech has used them many times and has never had an issue with any of their work. New motor 3x+. Ran it 4 hrs and gained 1/8" on the dipstick. Benton

Update: Tech coming tomorrow to check the fuel pressure modulator. I have a used aluminum 14.5x17P prop ($48.) to try. Also getting the cost of a powerhead if needed. Still trying. Benton

Dan, with our 4 stroke no one has ever mentioned fumes while in the cockpit. 2 stroke exhaust is awful imo. Benton

A correction on the prop size. The '23' is actually 'Z' 3. It is a 16 pitch PowerTech doesn't label their props as 14.5x16. I have sent a request for explanation of what prop I have.

Avidmagnum12 and others: I just checked my prop and it is a PowerTech 23R16P CL200 This is a bit larger than yours, isn't it? Typically I cruse at 4100 rpm and 26-28 mph. 3.0-3.4 mpg on the Yamaha gage. Tech is supposed to come today to check Fuel Pressure Regulator As you can tell by my profile...

Thanks for these replies, and sorry for the delay getting back into the site. 1. For clarification, "making oil" is a mechanics term for gas getting into the crankcase and increasing the amount of 'oil' in the engine. Water in the oil is easy to see. 2. The low initial compression and leak down...

Well I just want to give an update on my Yamaha oil making saga. My tech has been a bit slow so Finale has been sitting on the trailer. The new computer didn't have any impact on the issue. We are going to check the fuel pressure regulator next week. My tech says if that isn't the problem...

Well it's not the computer. Brand new computer with 0 hrs. on it. Bad news is I met a Yamaha shop foreman and told him my story on making oil. He said the computer wouldn't fix it( right about that) but says he knows what will. If you met this guy you would understand why I don't like him, at...

Dr. Bob Both the low and high pressure electric pumps are outside the engine. Also, if the VST float level is incorrectly set and it overflows, that goes up to the canister and then overboard through the lower cowell. The tech has felt the computer is keeping one or more of the jets open. There...

Well here is a twist to my making oil issue. My new tech ran compression and bleed down with me present. The reason my engine runs good is....I have a perfect engine. Compression 220# on 3 and 210 on the other. Leak down was 100% on all 4. This tech has felt the computer could be the issue but...

Steve and others, My bust the compression the first tech was 95# in all 4 cyl. Senior Moment :roll: Benton

Steve, The thermostat was the first thing I checked and it had totally failed. I never noticed it running cold however. After replacing, the temp is dead center on the gage. I just got the appt to run the compression and bleed down tomorrow afternoon. We'll see if the first numbers are confirmed...

As follow up to the responses, there has never been any water in the engine. The oil was black and no brown look or cream look. My first thought was on the 10 qt that the dealer serviced and someone filled it twice. That was wrong. I have put marks on the dip stick at 1/4" spacing to see how...

Thanks for the comments from the group. I can say: 1. My boat is on a lift so I almost never tilt the engine up. The first I knew I had an issue was when I checked the oil and oil ran out the dipstick hole and I extracted about 10 qts out. Apparently I didn't check the oil as I should have. 2. I...

Bob and others, After reading your responses: I have made some calls to some independent, certified, Yamaha mechs to see what they might offer. If they don't do machine work they likely 'know a guy'.
