E TEC or 4 stroke.

[Pelicano]

I have decided to repower my polar 17 CC with a 90 hp or 115 hp 2007 engine. Been looking at the e tecs and the Yamahas and suzukis. I think im sold to the e tec due different factors..one of them is the weight factor ..second 2 stroke new techonlogy. does anybody out there has any idea how much extra i have to pay for rigging the motor ...controls gauges cables prop oil and everythng else is involved to get it ready for the water? ANy web sites out there that can give me some current pricing...most of the web sites dont have prices on thes new motors . ALso i heard of the spring sale evinrude is having....2 dollars off per HP? is that it?....that doesnt sem much... i know it is something but come on....

any info will be appreciated thank you.

Re: E TEC or 4 stroke.

Let's deal with the two stroke vs. four stroke thing first. What do you prefer? Two stroke EFI is still on the market. You can get very reliable motors from every manufacturer. Most are sequential injected motors where the injectors fire on every intake stroke so the mixture in the intake manifold is fresh with the air coming in as the intake valve opens. The ETEC is direct injected meaning the injector fires directly into the cylinder just as the piston closes off the exhaust port. There is a lot less oil consumption here, a lot better fuel economy and just as much power plus you don't get the smoky exhaust.

Four strokes are quieter, and somewhat smoother running engines. They don't rely on mixing the oil and gas. However what you lose is power. You'll get just as much oomph from a 90 HP two stroke as you will in say a 115 HP four stroke. I'm fairly certain Evinrude hasn't made a four stroke yet. Suzuki four strokes are really reliable.

You will be amazed at the torque and performance of the 115 E-TEC. It is the best of the E-TEC family in all around smoothness and quietness.

2 stroke all the way. Loads of power. Those 4 strokes are nice.

Re: E TEC or 4 stroke.

Figure about $700.00 for rigging. Here's a site with some prices..

Re: E TEC 90 hp prop advice

Thank you all for your responses. I did get the E TEC 90 HP , I took my boat in friday and should be ready sometime next week. The motor will be set for the xd 100 oil as well .

But now, im reading about different props and all what do you guys have in yours nad how do i konow how to choose the right one/brand and so on. I heard a 15" pitch will give you more efficiency...what do they mean by that? (gas , speed ?...) whats the diff. between a 3 and a 4 blade. etc, Thank you again and as you know, e tec owners, I can't wait to try this new motor out.
ps: wow!!!!...the grass already is looking greener and the sky bluer and my wife prettttier all of a sudden.

Let's Talk Props

Let's Talk Props

How convenient that I am just starting the next six week module of my marine tech certification classes. We're doing rigging and performance and our "project" is a 19' Grady dual console. We'll be stripping it bare of everything, gauges and all. Then we'll re-wire and re-power with a brand new Suzuki 150. Can't wait. First thing you need to tell the guy putting the engine in is how you use or will use the boat.

Colleges can offer full semester instruction on prop selection, prop technology and the who's, what's, why's, and wherefore's. Your new motor is going to have certain specifications as far as what rpm it should be spinning at full throttle. So after you properly break in the engine, you'll want to take it out, get it up to full throttle and see how fast you're going in speed and in rpm. The ETEC 90 will probably want to run at 5500 rpm give or take a 100 rpm here and there. You have a small center console so it probably won't take much to get it up on plane. If you're flying at like 35-40 mph at 5500 rpm, that is probably where you want to keep it. I wouldn't want to take a small cc any faster.

Props are weird things. 15 pitch means that one full revolution of the prop should push your boat 15" in the water. Every prop also has a correction as to how far it actually pushes. Sometimes pitch sizes are trial and error. You may be setting up a certain boat and you're sure the pitch should be some small number. Then you find out that its like a 22 pitch that makes it run nicely with a four blade prop.

1" of pitch = approx 100 rpm difference.
Each blade is worth approx 1" of pitch.
Prop diameter is worth approx 1" of pitch.

I could go on for hours. Nobody wants to read my babble. We haven't even touched on the angle of the blades, stainless vs. aluminum, the cut of the blade, the angle of the blade in relation to the prop shaft. Prop conversations among boat makers and marine mechanics is like a bunch of lawyers at a convention. You can debate the topic a hundred different ways and nobody is more right or wrong than the next guy.

Re: E TEC or 4 stroke.

Put 175 miles on the water this past week and had lots of four stroke and E-tecs to listen to. At wide open throttle there is no significant difference in noise between the two. I will say however that the E-tec sounds sweet compared to the four strokes that seem to have an "I'm struggling" note to them. 15P on that size boat seems way too little pitch. I run a 19P on a 75 Merc on a 17 ft walleye boat. The E-tec should be really happy with at least a 19 and probably a 21P unless the boat is heavier than I think it is. Four blade props are smoother and provide better hole shot than three blades. However prop selection is a crap shoot. Prop styles, prop material, and even props with the same number of blades and pitch from different manufacturers will perform differently on any given boat. Work with your engine dealer as they may allow you try several different props. But then be a sport and buy from them when you find one you like.

Re: E TEC or 4 stroke.

Thank you for all the information guys. That was great. I havent get my boat back yet but I will try the prop (aluminum) they are putting on it first. At least thats what they recomended and probably wont' need another one they said (except fpr a spare). They said : "be prepared" "your boat will take off like a motorcycle" "have your hat turned backwards too" if thats the case then I might have to get some kind of seatbelt or something...are these e tec that really fast outta the whole?...wow!

Also what do u guys know about this props that are composite? (is that it?)>>>you can actually change blades one at the time when it gets demaged. Thank yo againg you all for your answers.

Re: E TEC or 4 stroke.

I mainly ran an aluminum prop. Mainly because I wasn't sure of the waters and my Ranger came with a Stainless. I was worried about hitting rocks. Well today I put the stainless on. After reading the post about prop pitch and more on the blade themselves I want to look into the props I have more. For instance..without knowing all about the prop...my hole shot with the stainless was significantly more. Normally I come out of the hole and get it up on plane and quickly to 35mph. With the stainless I did the same and I was at 50mph.

Re: E TEC or 4 stroke.

Guys thanks again for your responses. Here i Have another one. On the TACHOMETER . the shop said they will put and standard one. What i didnt ask was...how standard that is...will it read motor hrs? temp. (rpms, mph, obviously) oil level ..what else trimming maybe? ..what else/..analog or digital..does anybody know? is there a web site i can look at?..looked on the eveinrude site couldnt find it. Thank you again.

They have loads to pick from. You may want to get more specific. I think cosmetically guages look nicer than others depending on your boat.

Re: E TEC or 4 stroke.

Sorry forgot to answer...they would be installing just the tach.

Congrats on the E-tec. I just installed one also - a 90 hp. After about 10 hours, it has run perfectly. Starts on the first turn every time, warm or cold. I'll keep my fingers crossed, but I'm pleased so far!

About tachs, you may know this already, but you have to have a Systemcheck guage or a tach with one installed in it already to preserve your warranty. I wanted the one of the Evinrude I-Command tachs, the classic one, and was told that they are not installable on my motor and my only choice was the regular Analog tach with Systemcheck which is what was installed. I-Commands are available in the Classic version (analog) or the digital one on the 115HP and above. I was told there was talk that they would be available in the future for my motor.

Good luck with the motor!

Re: E TEC or 4 stroke.

Yesterday friday I got a late phone call from the shop saying the boat will be ready arund 4pm/ got there 4.30 went through all the paper wk. and got the boat. First impression was the size of this 90 E tec. wow !!! I really liked that inmmediatley.. My Suz DT 90 was at least 1/3 bulkier.... The e tec shiny clean white makes look my small boat bigger. Opened the /hood/coil....and mmmmmmmmmmm!!!! that brand new smell guys....it was something else.....I studied the layout for a while then proceeded to cover up again. Weather its been kinda rough the past three days around here so I havent' get to try the engine just Yet. The dealer put a Systemcheck guage , an hr meter and had a second bilge pump installed. I wasn't that much happy with the rigging of the bilge pump at all..they just pulled the hose next to the steering/box controls over the transom... I expected different at that..... have to talk to them about that monday.But any how...
I installed back the GPS and worked fine...the fishfinder (Raytheon LG something) did NOT. I m not sure what it is...i saw a flick of darkish blaanketing the screen for a second or so and that was it...i dont know wahst going on there. I checked all the fuses and wireing to the battery terminal and it seems to be fine....maybe a loose connection...but nothing..tried it and same thing happeed....


Tomorrow sunday hopefully will be a better day .....and will get to try the boat to see what it does.
