I had that exact same boat for many years. 4.3LX with a 21 pitch mirage-plus was the best over all combo. I tried a lot of props on that boat 4400 RPM low 40's GPS verified with the stock alpha1 drive. I did a little work to the engine though, added a 4 barrel ect.
I would suggest you get a...
I was wondering what the WOT range is on this motor.<br />My manual only says 5000 rpm.<br /><br />Usually mercury gives a rpm range.<br />The tag on the tilt and trim doesn't have anything but the serial # and weight.<br />My old motor had max rpm also.<br />Thanks
I have an opertunity to buy this motor for $650.00<br />It is in great cosmetic shape and seems to run well.<br />Other than standard waterpump/lower unit maint this motor looks untouched.<br />How does this motor compare to a merc of the same vintage?<br />It looks like the same motor to me.<br...

Hi guys,<br /> I have a 1996 75hp merc on my starcraft now.<br />I am looking to upgrade power and ran across a super clean 1998 force 120hp for 1800.00<br />The motor has good compression in all 4 cyl. and runs like a top.<br />I figure with what I can get for the merc(great running motor...
Can anyone tell me what the difference is in these 2 motors to make the 90 more powerful?<br />They both have the same bore/stroke weigh the same and as far as I can tell use the same short block. Is it the carbs, reeds, or what?<br />Thanks
Hi guys,<br /> My buddy just bought 2005 crestliner sportfish 1850 and powered it with only a 115(rated for 175max). I don't know what wot is for this motor and the marina he bought it at rigged it with a 19 pitch. He turns right at 5K at wot. What is factory recomended range on this motor?<br...
My friend just bought a new boat and sold me his old beat up one for $500.00<br />The bad news is the motor has no reverse(hit a rock) and he has been using it this way for at least 6 months.<br />I figure I need a lower unit.<br />Should I try to have this one rebuilt?<br />How much does a...
I have a 2003 17 ft glastron 4.3 mercruiser 190 hp carb motor with a little over 2oo hrs on the stock plugs. I thought I would change out the plugs. After pulling and reading the plugs I found the following readings.<br />cylinder 1 and 2 were somewhat lean(white electrode with a little...
I was wondering what WOT rpm should be on this motor? I will be getting this motor from a buddy when he repowers his boat with a honda.<br />I plan on using this motor on a klamath 18' aluminum fishing boat and need this info to prop it right.<br />Thanks
Hi there,<br />I went fishing with my buddy this weekend and when backing off the trailer the boat wouldn't go into reverse with out grinding. When you add power the motor grinds but when you put it in reverse at idle it goes in. He told me he hit a rock with the prop last time out and it has...
Gelcoat scraped off keel of boat.
I have a small area(1/2"W X 3"L)on the keel of my boat where the gelcoat has scraped off. I also have a couple of real nasty gouges in the front where my dingbat father hit the end of the dock. Can I fill these in with marinetex then sandit smooth once it...
I have a 1999 Gmc suburban with a 5.7L vortec v-8.<br />Since I have owned it since 40k miles I have changed the oil every 5,000 using synthetic 5w30 and I have always consumed 1 quart per oil change. Last oil change I checked at 3000 miles before driving it on a 300 mile trip and was 2.5...
Hi all<br />I am looking at a 1979 glastron Hpv-160.<br />The floors are soft and I imagine the stringers are toast also. It belongs to a guy I work with and I could pick it up for a few hundred bucks with a good trailer and mercury 110 hp outboard. I think the motor is a little older than the...
