Whether you’re a seasoned mariner or a leisurely weekend cruiser, the choice of an outboard motor can make or break your experience on the water. Yamaha, a renowned name in marine engineering, has long been synonymous with quality and dependability in the realm of outboard motors. Today, we explain the process to survey a Yamaha outboard motor, what to look for, data taken and how to interpret the data.

Yamaha’s Technological Advancements

At the heart of Yamaha’s outboard motors lies a dedication to pushing the boundaries of performance, reliability and efficiency. With advanced  technology and dependability, Yamaha has consistently delivered engines that not only meet but exceed the expectations of boaters worldwide.

One of the standout features of Yamaha outboard motors is their legendary reliability.

Whether you’re embarking on a solo fishing expedition or a family outing, having a dependable outboard engine is crucial for peace of mind on the water.

Moreover, Yamaha’s commitment to environmental sustainability is evident in their range of eco-friendly outboard motors. With advancements in fuel efficiency and reduced emissions, Yamaha engines not only offer top-notch performance but also minimize their impact on the marine ecosystem.

Insights of the Yamaha Outboard Survey

Conducting a survey Yamaha Outboard in Ft. Lauderdale should be done by a Qualified, and Authorized Yamaha Outboard Technician. Beware of imposters or technicians who say they are “Certified”.

This is what we at Yate Parker  in FT. Lauderdale look for.

The survey should start on land with access to all parts of the outboard.

  • Write down boat and engine specs on spec sheet. Take pictures.
  • Perform computer down load. Delete codes (Note).
  • Perform compression test.
  • Check condition of engine block anodes, note condition.
  • Check engine oil, note condition.
  • Drop and drain fuel/water (Note condition).
  • Check lower unit oil, note condition.
  • Check condition of engine appearance, note condition.
  • Check external anodes, note condition.
  • Check props, check shaft runout.
  • Remove prop(s) check for fishing line, condition of SDS Damper.
  • Drop lower unit if exhaust section is to be inspected.
  • Run engine on hose, bring to operation temp, 113℉, take computer running download, shift engine. (Prop) removed.
  • Take pictures of the engine, exterior, damages, prop(s), size.
  • Supply the Buyer with a written report as well as engine downloads.
  • Service logs on Downloads?
  • Supply the buyer with Warranty Expiration and any previous Warranty claims on the engines..
  • Taking the vessel out on a seatrial is not really necessary with the Yamaha Technician on board, unless the buyer wishes so, or there are concerns on the engines. It is important to note the WOT RPM of the engines whilst running.


What to look for and interpreting the data:

Like most things in life, first impressions and aesthetics are important. If it looks clean and taken care of, it probably is. If it doesn’t, it probably isn’t.

Compression numbers:

  • While compression numbers may matter, the most important thing is that they don’t vary by each cylinder PSI by more than 10%.


Yamaha Engine Download data:

  • When reviewing downloads. Hours at RPM’s are important. Does it have the majority at idle or below 200RPM? This can lead to Carbon build up.
  • Are there high hours at high RPM’s? Long hours at high rpms can lead to premature engine wear.
  • How many over revolutions counts? None. Good. Many? Look as to why. Engine height? Correct prop size?
  • Are there any overheat counts? None? Good. Many? Why?
  • Any Low Oil pressure counts? None. Good. Any? Why?
  • Service logged into E.C.U?


Yamaha Warranty and Warranty Claims:

  • How much standard Yamaha Warranty remains? Great for peace of mind.
  • How much Y.E.S (Yamaha Extended Service) remains? Better for long term peace of mind.
  • What are the previous warranty claims? Small items? Normal. Major items? Ask why. Another reason to use a Yamaha Authorized Technician/Shop.



Read what the engine is telling you.

  • Oil fresh? Worn? Water in oil?
  • Lower units. Oil fresh? Worn? Burnt? Water in oil?
  • Water in fuel?
  • Anodes in good shape? They should have 50% of life left by weight.
  • Engine hours. IMO higher hours over a consistent period of time is better than lower hours over a longer period of time.



Having a Yamaha Outboard engine survey in Ft. Lauderdale completed by a competent, qualified and Authorized Yamaha technician should be one of the most vital steps in purchasing your “New to you” previously owned vessel. While never knowing what tomorrow brings for the life of am outboard engine, that report should give you a good indication of its life and use  to date.

You will have noticed that I use the term “Authorized”. There is a difference in “Authorized” and “Certified”.

Authorized means they are an Authorized Yamaha Dealer. They use Yamaha Y.D.I.S Software. (Not aftermarket). Have access to Yamaha Y.M.B.S for Warranty related questions/issues.

Certified just means they took “A” class at either Yamaha or a Yamaha supported Technical Program. They do not have Genuine Yamaha Diagnostic software and they most times are not Yamaha Authorized with access to Yamaha on line data.
