Help for a beginner

[Frogman234]

Im a beginner. With basic knowledge of how a motor works (attended Marine Mechanics Institute) I want to learn more so I can follow what you guys are talking about in threads. I want to confidently mod my own motor too so when it comes time to ask questions I don't want to sound stupid. I quit MMI after 4 months because of financial issues but after talking to some of my friends who graduated they have no clue about modding motors or what a tuner is. I've actually learned more in a couple weeks of reading these forums than I've Learned in MMI. That makes me feel better actually cause I didn't waste too much money for school.*

So my question is this: Is there a thread or site where I can learn the basics of modding so I can follow what you guys are taking about?

I'm planning on getting a manual to my 99 Mercury 150XR6 motor before I do anything else to it. So far I've removed the oil pump and installed the plug so I can premix. I also removed the timing advance module and oil alert module is disconnected.*

Thanks

Keep reading it takes a long time, even a life time to gain the knowledge some here have. Remember no such thing as a stupid question, read all you can. Come up with a plan on how you want to mod your motor then post it here then you will be told if your moving in the right direction.

This may sound silly but study this and learn to understand the basic functions and parts. Modifications are not general but very specific. By understanding exactly what is happening and how you can pick areas you would like to improve on such as compression (cutting heads) or maybe exhaust scavenging (tuners) better flow thru reed valves (porting cages). The best way to learn and understand is to find a blown up motor and disassemble it. Your local marina may have a grenade you can get cheap. And like Dave said, read whatever you can find. You have the net so it is all at your fingertips. Welcome to the addiction.

You will get all of the help you want from here as long as you treat those with the Black-Belt knowledge with respect. It took them a long time and piles of money to get what you are asking for free. They are always glad to share with anyone who has a good attitude.
Merry Christmas!

JR nailed it and couldn't have said it better .

Here is a link that helps alot of beginners even the seasoned. There is simply a ton of information in there for both the novice as well as the HP crowd.

It will help you know what NOT to do, more than what TO do ... but at least you will understand why

Like JR stated...Make sure you are listening to a good source as well. Need to listen to builder and not to readers. Too many readers only take a small portion of a topic they read and try to share it and end up telling someone something that will result in a blown engine. It took me years to get where I am and I build a lot of modified engine. I still find I have to ask a question because I build all types and what works on one does not work on another. I will PM you some links with some detailed information on some of the common 2.5 mods. Welcome to S&F!!!!

dave strong up in post number 2 had it right. you don't become a guru by reading a book or a thread. it takes years, and plenty of hands on. don't get me wrong, you will need to read plenty, but reading is just part of what it takes. i didn't start really learning about motors until i got out of college and got a job where i had enough money to buy parts and replace motors that blow up because i did something wrong. you learn a LOT from your failures. well, that's how i learned as a "college boy" type.

if you are not a college type and more like a tradesman, that's even better, because probably the best way of all to learn is to get a job working for one of the gurus like our own s'n'f member, racer. I mention him, because he is on the west coast, like me and he's an OMC specialist and i like OMC's. this is an east coast site though, and there are a bunch of merc gurus out east as well. but you've got to stick with it and plan on making it your career if you go to work for one of the gurus. they'll probably start you off by making you sweep floors and only very slowly increase your responsibilities and trust.

good luck.

Yeah, I had a job at shop while I was attending MMI but I learned real fast that I don't want to work on boats for a living. Its a hobby of mine. I like mercury motors and bought 3 merc 115 inline 6 motors for about 100 each while I was in Florida. I was able to piece together 1 great working motor out of them and sold it. It was a fun project and a big learning experience for me. Finding this site has opened up a whole new world for me. Its awesome reading about what you guys do to these motors! It's like reading super hi tech sci-fi stuff except it's real. Anyway, I'm a follower for life now so just wanted to say to all you guys thanks for sharing all your knowledge with us noobies. We really appreciate it!

Sometimes it is just easier to get a bigger motor than mod the one you have. Keep that in mind. There are also some very easy mods to get more out of what you have. A new ECU can get you more RPM's. A different LU can get more speed and allow you to jack the motor up for less drag and even more speed. The only limiting factors are the size of your wallet and how much you can do yourself vs paying someone. The 2 mods I mentioned above are easily handled by anyone that can turn a wrench and pay for the parts.

This can get rather addictive.

I have done that for customers. They have a 2L 150 wanting it to have a ton of power on a heavy boat and I get a 2.4 200 block and all the needed parts for less than what I would have charged for the modifications and a lot further ahead of the game from a stock persective. Yes, it becomes addictive.

[Frogman234]

My block says 150-200 tho. What's up with that?
