    Slow cranking speed

    Could a very slow cranking speed cause a no spark situation? I noticed the motor I'm trying to get running cranks rather slow and draws a ton of current so I brought the starter to a rebuild shop to have it tested and they said the armature is shorting out. It "works" but its slow. I have no...

    Question before replacing all ingnition components on my XR4

    Re: Question before replacing all ingnition components on my XR4 Is this abnormal? Or just rusty? I ask because in my research I read that the flywheel hub has two stacked magnets and it looks like I only have one with space for another one. I cant imagine where it would be. I don't remember...

    Question before replacing all ingnition components on my XR4

    Hey folks. Heres the scoop. Upon reassembling my motor after a rebuild, I have no spark anywhere. Ran before but poorly (could have been a million reasons why) I've tested as follows. 150 volts at low speed wire on switch box from stator (should be 200-300) 15 volts on high speed wire on...

    Is 3M 4200 thicker than 5200?

    I'm getting ready to seal the cap back on the hull on my bass boat restore, and I'm noticing how runny 5200 is from doing other things. I bought two tubes of black 4200 to seal the joint between cap/hull but if its as runny as 5200 its just going to be a big failing mess. Is 4200 what I want for...

    Question about V6 head. Not sure about the advice I just got from a boat shop.

    Im in the final stages of my rebuild on my 89 150 xr4. The machine shop said one head was warped .011. The manual says the max I can take off is .010. I went to a boat shop to see about a used head and he said just to run it as is. He said he never has checked a head for flat and thinks that the...

    Through hull livewell fittings

    Hey folks. I purchased all 3 new livewell thru hull fittings for my bassboat today and when I got home I noticed they said "not for below water line". These will obviously be below the waterline. I'm wondering if it really matters or if that's a "lawyer disclaimer". My boat is trailered and not...

    Anyone running an aftermarket stand alone engine management on an outboard?

    A few years back I did a motor swap on my 92 vw to an Audi A4 20 valve turbo. I used a stand alone engine management system which totally allowed me to tune everything from a laptop including timing and fuel map. Just wondering if anyone has run something like this on an outboard? Given the cost...

    What are we putting cases together with?

    I'm getting ready to put the case back together on my XR4 rebuild. I'm referring to the second half of the crank case. The part with the main bearing caps. The manual says to use loctite master gasket #203. Havent looked for that but figured I'd ask if its the best stuff to use or if theres...

    Rebuilding an XR4. Piston Questions

    Hey there. I have a 2.4L 150 hp XR4 I'm building. It needs one new piston and to be bored the next size on that cylinder. My question is about pistons. Looks like I can get a set of Wiseco pistons for around 800 ish. I assume this includes rings and pins. It will cost me approximately 450 for a...

    Ballsy, stupid, or a fantastic idea??

    Ok folks. Here's the scoop. My family has a house on an island in Narragansett bay in Rhode Island. A "normal" boat ride is about 10 minutes give or take depending. My father and I are thinking of making an early run out there this year to do some brush cutting before it grows too deep. (this...

    1989 Bass Tracker Fiberglass full restoration.

    Hello. I've posted bits and pieces on here but I figured I'd do a full resto thread and make it official. To this point I've gotten the cap off, the floors and foam out and a new transom glued in, waiting for glass. I've never done this before, so please, if you see me doing something stupid...

    Quick question about a wierd transom cut

    Hey guys. I'm done with the demo on the transom area and it's time start construction. The old transom piece had a SEVERE angle on it where it met the two side panels. The main transom board was double 3/4 and the two side panels were half inch scraps (you might remember the thread I started...

    OMG it was so big. But I need a suggestion.

    Hey guys. My buddy and I had one of the best nights of fishing we'd had in a long time last night. We left the dock about 6pm. By 8 we had around 15 bass between us ranging from 2 to 4 pounds. Not bad. Especially for us! I run 12 lb line and the 4 pounders would take some line when they ran...

    Impeller change. 2006 50 HP 4 stroke Bigfoot

    Hey folks. I'm selling my pontoon boat (hopefully) but I want to do an impeller change on it before it hits the water. I bought the boat new and have not done an impeller yet. I don't want to buy a manual for this motor because I don't expect to have it that long. I've done a couple other...

    Can you tell the approximate age of this outboard?

    Hey guys. I know you probably cant tell me much from this picture but for now it's all I've got. I was just wondering if you could tell an approximate age by it's looks. I mean like is it late 70s 80s etc. I may purchase it as a fixer for short money. Owner says low comp on one cyl. He doesn't...

    Where to find control parts.

    hey guys. The controls for my 88 xr4 are the ones with the seperate lever for high idle, and push to choke. I need a new warning buzzer and tilt switch for these controls. I've done some searching but cant seem to find these parts available. I'd accept them used if anyone has any laying around...
