Do "I" need to decarb?

marine supply — Sun, 05 Feb 2012 20:59:04 +0000

Here’s an interesting post from Do "I" need to decarb? :

I have a 2000 Evinrude 225 that has about 300 hours. Since I don’t fish the only time the motor is at slow RPM is in no-wake zones. Otherwise I run at 4000 – 4500+ RPM and at least WOT for a few minutes each time I am out.
I am using XD50 and Seafoam in every tank of gas.

Do I need to decarb the motor?

Thanks in advance!

Prop ?

marine supply — Sun, 05 Feb 2012 20:56:56 +0000

Here’s an interesting article from Prop ? :

Any suggestions appreciated.

36′ Stamas Express running healthy, new (long blocks) Mercruiser 502 Mag MPI’s with rated HP of 415 propped with Nibral 4-blades that have a slight cup

Runs very smooth with no vibration, good low speed handling, and jumps on plane when empty. Engine specs call for WOT RPM of 4,400 to 4,800 my WOT is 5,000

If I were to add more pitch or cup to bring down WOT what could I reasonably expect for an increase in speed and / or fuel consumption?

Should I leave “well enough alone” or do you think it would be worth the effort and cost of re-working the props?

225 OX66 gear oil overflow?

marine supply — Sun, 05 Feb 2012 20:46:42 +0000

Here’s an interesting article from 225 OX66 gear oil overflow? :

My ’99 225 OX66s have been on the lift for about two weeks with the engines trimmed full up. I lowered the engines to gain access to the bilge.

When I lowered the engine to the full down position a small trickle of clean gear oil came out of a hole located just above the “full level” plug .

With the boat in the lift I can not drain or check the lower unit oil. I have the boat scheduled to be put on the hard to work on it next weekend.

The leaked oil looked clean and not emulsified so I don’t think I have a lower seal leak, but with the engine sitting for 2 weeks the oil and water may have seperated out. I could find nothing in the service manual about this hole.

Any ideas?

Here’s a new article from Power-vent surface drive system :

Going through types of drives …came across these one!! Dose any one has more knowledge on this type of drives? See,s like a good alternative to the conventional drive system with (maybe) grater shaft/prop protection.

Etec 115 rough texture near lower unit

marine supply — Sun, 05 Feb 2012 11:12:03 +0000

Here’s a good article from Etec 115 rough texture near lower unit :

Attachment 218615

Was at the New Orleans boat show today and looked at the Etecs on display. Does anyone have a good explanation why the 115 hp model has this rough texture on it? Two dealers there said it was because of the lost foam casting method used. However, only the 115, and 40-60 hp models have this unusual texture. Seems like it would make it difficult to keep clean.

Nautic Star 2400 TE… WELL THOUGHT OUT!

marine supply — Sun, 05 Feb 2012 10:15:22 +0000

Here’s a good post from Nautic Star 2400 TE… WELL THOUGHT OUT! :

Well, after researching and asking for opinions on THT, I think I finally found the bay boat that I was looking for, assuming that the sea trial goes well. Today I looked at all the boats that were high on my list at the NOLA Boat Show. Out of Skeeter, Triton, Tidewater, Key west, Shearwater, Blazer Bay, and Pathfinder, I feel that the Nautic Star 2400 TE has the best all around package to offer for what I am looking for in a bay boat. This is a well thought out fishing boat that can get shallow and handle the waves on runs out to the rigs in Venice, LA. I was very impressed with the lay out on the NS, the way the boat was wired, and the ease of accessing the wiring, bilge pumps, etc. This boat has obviously been planned by fisherman who have paid a great deal of attention to the small things that a great fishing boat should have, without over doing it. My only questions are how dry does the boat ride, and how well does it handle the rough seas? I would appreciate any feed back from anyone who has personal experience with the NS line. Thanks for your time and interest.

Wiring Installation Problem w/New Motors

marine supply — Sun, 05 Feb 2012 09:33:14 +0000

Just finished installation of new 225 Optimax motors. Each engine has its own battery and battery switch, 1 2 Both and Off. Power from battery to switch and positive lead out of switch to starter of motor. Both batteries are tied together with a common ground. Individual smartcraft harnesses go to dash and terminate at a 6 way junction box. Off the junction box are the tachs for each motor and a common speedometer. PROBLEM: Starboard motor will not crank unless starboard battery switch is on AND port battery switch is on. (and vice versa) I think they are isolated from each other, unless something is being shared at the dash through the junction box and or speedometer. When both battery switches are on, everything is great. Where did I screw up?:banghead:

Good size for raw water strainer?

marine supply — Sun, 05 Feb 2012 08:56:39 +0000

I am rebuilding the starboard engine on my ’84 Silverton 40 Aft Cabin. Heat was an issue as both engines ran rather hot (180 port, 200+ starboard) when at high crusing speed/load. i am taking the “opportunity” of the rebuild to fix the cooling problem as well. Believe it or not, there are no strainers on either raw water inlet. We are replacing the intake valves and I wanted to add strainers before it enters the engine. Will Perko 493′s suffice for this? Im not sure what diameter the raw intake hose is (boat laid up for winter). Im guessing 1″. The engines are Crusader 454 350 XL’s FWC. Thanks!
